1.5 Glossary

Archive - An archive consists of one or more Data Sets along with all the documentation and ancillary information needed to understand and use the data. An archive is a logical construct independent of the medium on which it is stored.
Archive Volume - An Archive Volume is a single physical media (CDROM, DVD, 9-track tape, etc.) used to permanently store files within the PDS archive. Archive Volumes may only be created on media approved by the PDS as meeting archive quality standards.
Archive Volume Set - A collection of one or more Archive Volumes used to store a single Data Set or collection of related Data Sets.
Catalog Information - High-level descriptive information about a Data Set (e.g., mission description, spacecraft description, instrument description), expressed in Object Description Language (ODL), which is suitable for loading into a PDS catalog.
Data Product - A labeled grouping of data resulting from a scientific observation, usually stored in one file. A product label identifies, describes, and defines the structure of the data. An example of a Data Product is a planetary image, a spectral table, or a time series table.
Data Set - A Data Set is a collection of Data Products from a single instrument that have a common data processing level, together with supporting documentation and ancillary files.
Standard Data Product - A Data Product generated in a predefined way using well-understood procedures, processed in "pipeline" fashion. Data Products that are generated in a non-standard way are sometimes called special Data Products.

1.6 Content Overview

The Ion and Neutral Mass Spectrometer (INMS) aboard the Cassini spacecraft consists of a closed ion source and an open ion source; various focusing lenses; an electrostatic quadrupole switching lens; a radio frequency quadrupole mass analyzer; two secondary electron multiplier detectors; and the associated supporting electronics and power supply systems. The INMS will be operated in three different modes: a closed source neutral mode (CSN), for the measurement of non-reactive neutrals such as N2 and CH4; an open source neutral (OSN) mode, for reactive neutrals such as atomic nitrogen; and an open source ion (OSI) mode, for positive ions with energies less than 100 eV. The primary focus of the INMS investigation is on the composition and structure of Titan's upper atmosphere and its interaction with Saturn's magnetospheric plasma. Note that the INMS 'Closed Source' mode only measures neutral particles so 'neutral' is redundant when referring to this mode. However CSN is used throughout this document so that file naming conventions are the same number of characters for all modes. INMS is a complex instrument, and will be taking data continuously throughout the tour phase of the mission (the exception being the release of the Huygens Probe and the associated quiet period, during which most instruments on Cassini will be turned off). This complexity, coupled with tracking the minute changes in the characteristics of the instrument over time, mean calibration data and calibration techniques will be dynamic. For this reason it will be impractical to redeliver data volumes as calibration improves. The solution is to deliver a data set that has scaling factors applied (i.e. converted to engineering units), and provide the calibration data as a separate ancillary volume. Thus, as calibrations improve, only the reference volume will need to be redistributed.

Each of the three modes of the INMS will produce packets containing total counts per sample. The number of integration periods that are co-added to form a packet depends on the rate at which the instrument is taking data.

INMS data will be divided into three data sets, one containing telemetry packet contents converted from data numbers to engineering units, one containing detector data annotated with instrument state and geometric data, and a third containing higher level data produced from the lower level data. The data sets may contain one or more product types, which correspond to collections of related data in files of specific organization. The two high level data sets contain one product type apiece, whilst the low level data set contains one product type for each telemetry packet. The data set identification, CODMAC levels, and product types are enumerated in Table 5.

Table 5: Relationship Between Data Sets and Standard Data Products

CO-S-INMS-2-PKT-U-V1.0	2	INMS_PKT_SCI INMS_PKT_HKG INMS_PKT_HMD INMS_PKT_SMD	Telemetry Packets with contents converted from data numbers to dimensional quantities
		INMS_PKT_OTS	Operational table description

The data set CO-S-INMS-2-PKT-U-V1.0 contains the contents of the INMS telemetry packets, with each variety of packet forming a product type. INMS produces 4 packet types, Science (SCI), Housekeeping (HKG), Science Memory Dumps (SMD), and Housekeeping memory Dumps (HMD). An additional data type, OTS, is included in this data set which contains information describing the operational table set controlling the data collection.

The data set CO-S-INMS-3-L1A-U-V1.0 contains annotated detector signals as a single data type. The data is aggregated from the science and housekeeping telemetry, spacecraft ephemeris and attitude data, Saturnian system ephemeris, and operations table contents. This data is provided as the fundamental data from which to produce higher level products. Besides the data files, this data set includes graphical browse products and a calibration summary valid at the time of volume creation.

It is anticipated that the data set CO-S-INMS-5-TTN-C-V1.0 containing altitude profiles of atmospheric species abundances, will be produced from data analysis preformed by the INMS science team and archived on a best-effort basis. The contents of this data set is related to Titan's atmosphere and will contain profiles of both neutral and ion species, included in Table 6 and Table 7, along with derived temperature profiles. Additional data product types may be added to this data set as the analysis results merit. Possibilities include magnetospheric ion and neutral flux as a function of look direction, space, and energy for each species. Magnetospheric constituents which INMS is capable of detecting, consist largely of water products: For the inner magnetosphere, ions such as H₃O⁺, H₂O⁺, O⁺, H⁺, OH⁺, and neutrals such as H₂O, H, OH, O (though OH and O are both highly reactive neutrals, and thus may not be present at detectable levels). For the outer magnetosphere, ions such as H⁺, N⁺, N₂⁺, H₂CN⁺ and/or C₂H₅⁺, and neutrals such as N, and N₂. At the icy satellites, INMS expects to detect species similar to those in the inner magnetosphere, along with additional trace species.

Table 8 contains a list of targeted flybys for which INMS is currently prime. When INMS is the prime instrument, the spacecraft pointing design was specified by the INMS team to support INMS data collection goals. The inner magnetosphere passes are still being determined in the science planning process, thus this list stops at Rev 46 (where the planning process is at the time this document was written). However, since these types of encounters are typically on the order of 90 minutes to two hours, this will be a relatively small subset of the INMS data.

In addition to the data sets outlined above, INMS will be producing and archiving a reference volume. This volume will contain the documentation that describes the INMS instrument and investigation. It will also contain the detailed calibration report. This report, contained in the CALIBRATION directory is the structured collection of document files, data files, command sequences and programs used to perform the characterizations of the flight and engineering model. Additional engineering model characterization activities are possible. In that event, the calibration report will be extended and the reference volume re-issued.

Table 9 contains estimates of the INMS monthly deliverable data volume, as well as a maximum possible. The L1A volume is computed based on INMS operating at full telemetry rate approximately 3 days per month and at reduced rate for the remainder of the period. Browse product files are negligible in volume compared with the data files.

1.9 Audience

This specification is useful to those who wish to understand the format and content of the INMS PDS data product archive collection. Typically, these individuals would be software engineers, data analysts, or planetary scientists.

2. ARCHIVE VOLUME GENERATION

2.1 Archive Structure and Identification

PDS data set names shall conform to the following format: CASSINI INMS DATA V.. For example, version one of the L1A science data set will be named CASSINI S INMS L1A UNCALIBRATED DATA V1.0.

PDS data set identifiers (dsid) will be abbreviated versions of the data set names formed according to the PDS formation rule for the DATA_SET_ID keyword. For example, the dsid for the data set above would be CO-S-INMS-3-L1A-U-V1.0.

Each data set making up the INMS archive is contained in a distinct set of physical volumes. At the PPI node, each data set is maintained on-line. The off-line archive for each data set consists of a series of volumes, each bearing a unique volume identifier. The volume identifiers consist of the mission and instrument prefix and a volume identification number as follows:

COINMS_Dnnn

where COINMS is the instrument prefix, D indicates the data set to which the volume belongs and nnn is a sequential number assigned to each volume. The values for the data set indicator are specified in the Table 10.

Table 10: Volume Identifiers
Data Set ID	Data Set Indicator D	Example
CO-S-INMS-2-PKT-U-V1.0	0	COINMS_0001
CO-S-INMS-3-L1A-U-V1.0	3	COINMS_3001
CO-S-INMS-5-TTN-C-V1.0	6	COINMS_6001

Data file names are formed from the date and type of the data according to the convention in Table 11. The names of INMS_SCI, INMS_L1A, and INMS_TTN type files, which contain one hour of data contain the hour in the file names. The names of the remaining data types, produced once per day, have "00" in the hour field of the name. All file names include a version number, which is a sequentially assigned number, beginning at 01. The version number is incremented when the contents or format of the file is changed. The relationship between the various identifiers is illustrated in Table 12.

Table 11: Data File Naming Convention Filename format: yyyydddhh_ttt_ vv.CSV
Identifier	Description	Options
yyyydddhh	Start time of data file	yyy - Year ddd - Day of Year hh - Hour
ttt	Data type	L1A - Science data annotated with ancillary data TTN - Titan atmosphere profiles SCI - Science Data Packet contents, scaled HKG - Housekeeping Data Packet contents, scaled HMD - Housekeeping Memory Dump Packet Contents, scaled SMD - Science Memory Dump Packet Contents, scaled OTS - Operational Table Descriptions
vv	Version number of data	01, 02, ..., etc.

Each archive volume has the same general structure, consisting of a set of fixed top level directories, INDEX, DOCUMENT, CATALOG, CALIB, DATA, BROWSE and optionally EXTRAS, the contents of which will be described in detail below. The BROWSE directory is only part of the CO-S-INMS-3-L1A-U-V1.0 data set. The EXTRAS directory contains files that are helpful but not required for interpretation of the archived data. Only the INDEX, DOCUMENT, CATALOG, EXTRAS and CALIB directories will exist only on the first physical volume of a data set to avoid the requirement to redistribute all physical volumes if the contents of either the EXTRA or CALIB directories change.

The relationship between the data set, standard data product identifiers and file names are illustrated in Table 12. The data structures for the archive volumes for data set are shown in the Appendixes.

2.2 Data Production and Transfer Methods

The INMS standard product archive collection is produced by the INMS instrument team in cooperation with the PDS Planetary Plasma Interactions (PPI) Node at the University of California, Los Angeles (UCLA). The INMS team is funded by NASA through the Cassini Project office and the PPI activities are funded by the NASA Planetary Data System.

The INMS team produces the individual data files and the associated PDS labels for each of the standard data products defined in section 1.6 above. Data files will all be comma-separated value, ASCII files containing all data of the appropriate type for the time interval contained in the data product. Data products will be compressed (Gzipped) and transferred via secure FTP to the PPI node. Each data transfer is logged in the Cassini Archive Tracking System, CATS. Upon notification of the data transfer provided by the CATS, the PPI node decompresses the transfer and compares its contents against the CATS transfer information. Each data file is validated against the MD5 checksum contained the corresponding detached label. The PPI node will post a positive or negative acknowledgement of the data receipt on CATS. If the acknowledgement is positive, no further action is required on the part of INMS. If the acknowledgement is negative, the transfer is repeated.

2.3 Archive Volume Creation

PPI collects the data files and labels provided by the INMS team onto archive volumes. Each archive volume contains all INMS data available for the time interval covered by the archive volume. Once all of the data files, labels, and ancillary data files are organized onto an archive volume, PPI adds all of the PDS required files (AAREADME, INDEX, ERRATA, etc.) and produces the physical media.

2.4 Volume Validation Methods

Validation of the INMS data archive is completed in two phases. The first phase is performed by the PPI node and consists of reviewing a sample data set for compliance with the PDS standards. The INMS team will submit a set of data files following the procedure of section 2.2 above. Upon receipt, the PPI node will confirm the structure of the files and labels. Once the sample data is validated, PPI will develop software to generate subsequent data volumes in an automated fashion. The second phase of the validation consists of a peer review to ensure usability and completeness. The peer review panel will consist of members of the instrument team, the PPI and Central Nodes of the PDS, and at least two outside scientists actively working in the field of mass spectrometry or planetary atmospheres. The PDS personnel will be responsible for validating that the archive volume(s) are fully compliant with PDS standards. The instrument team and outside science reviewers will be responsible for verifying the content of the data set, the completeness of the documentation, and the usability of the data in its archive format. Any deficiencies in the archive volume will be recorded as liens against the product by the review panel. After all liens placed against the product or the product generation software are resolved, automated production and validation can begin. Once automated production begins, the data file content will be spot checked by members of the INMS team. Browse products corresponding to the L1A product will be produced routinely and examined by members of the INMS team. In addition, the data will be actively used by team members to perform their analysis. Any discrepancies in the data noted during these activities will be investigated. If the discrepancy is a data error, the response will depend on the source of the error. If the error is in the software producing the data product, the error will be corrected and the data products affected will be reproduced. If there is a correctable error in a data file, the file will be replaced. If an error in a data file is uncorrectable, the error will be described in the cumulative errata file included on each volume in the volume set. The structure of data files and labels will be spot checked by the PPI node for compliance with PDS standards and this SIS.

3. ARCHIVE VOLUME CONTENTS

This section describes the contents of the INMS standard product archive collection volumes, including the file names, file contents, file types, and organizations responsible for providing the files. The complete directory structures are shown in Appendix A, B, and C. All directories and ancillary files described herein appear on each INMS archive volume, except where noted.

3.1 Root Directory Contents

The following files are contained in the root directory, and are produced by the PPI Node at UCLA. With the exception of the hypertext file and its label, all of these files are required by the PDS Archive Volume organization standards.

3.2 INDEX Directory Contents

The following files are contained in the index directory and are produced by the PDS PPI Node. The INDEX.TAB file contains a listing of all data products on the archive volume. In addition, there is a cumulative index file (CUMINDEX.TAB) that lists all data products in the INMS archive volume set to date. The index and index information (INDXINFO.TXT) files are required by the PDS volume standards. The index tables include both required and optional columns. The cumulative index file is also a PDS requirement; however, this file is not reproduced on each data volume. An online and web accessible cumulative index file is maintained at the PPI Node while archive volumes are being produced. Only the last archive volume in the volume series will contain a cumulative index file.

3.3 DOCUMENT Directory Contents

The document directory contains documentation that is considered to be either necessary or simply useful for users to understand the archive data set. These documents are not necessarily appropriate for inclusion in the PDS catalog. Documents may be included in multiple forms (ASCII, PDF, MS Word, HTML with image file pointers, etc.). PDS standards require that any documentation deemed required for use of the data be available in some ASCII format. Clean HTML is acceptable as ASCII formats in addition to plain text. The following files are contained in the DOCUMENT directory and are produced or collected by the PPI Node.

3.5 CALIB Directory Contents and Naming Conventions

The calibration directory, included in the CO-S-INMS-3-L1A-U-V1.0 data set only, contains one or more spreadsheets of instrument calibration data. An additional file will be added when the instrument characteristics have either changed or been more precisely determined. The files will be named according to their time range of applicability. For example, if it is determined that the calibration after 2007-030 is sufficiently changed, a file incorporating that date in its name will be added. The naming convention is defined in Table 17, below. To avoid the requirement of redistributing all physical media data volumes in the event of a calibration update, the CALIB directory will be present on only the first physical volume COINMS_3000, and a note to that effect will be placed in the AAREADME file on all physical volumes.

Detailed documentation of the preflight characterization is contained in the EXTRAS directory.

The CO-S-INMS-2-PKT-U-V1.0 archive volumes will have SCI, HKG, OTS, EVT, SMD, and HMD files in daily subdirectories The CO-S-INMS-3-L1A-U-V1.0 archive volumes will have L1A files in daily subdirectories. (see 3.6.2. for details description of this directory structure).

3.6.1 Required Files

Every subdirectory beneath the data directory contains a file named INFO.TXT that is an ASCII text description of the directory contents. Every file in the Data path of an Archive Volume must be described by a PDS label. All labels will be detached, having the same root name as the file they describe with the suffix ".LBL". In directories where there are multiple data files with the same internal table structure, the table column description is included in a single format file (.FMT) that is referenced by a pointer within each PDS label file. This prevents the needless repetition of information that is not changing within the PDS label files.

3.6.2 DATA Directory Contents

The data directory contains a separate subdirectory for each day. The daily subdirectories are grouped by year into yearly directories. The structure may be seen in Appendix A. The yearly directories will be named for the year, 2004, 2005, and so forth. The daily subdirectories will be named with the ordinal day-of-year, 001, 002,...366. There may be more than one SCI, or L1A data file in each subdirectory, depending on what events take place on a given day. For HKG, OTS, SMD and HMD only one file will be produced per day. In addition to the data files there will be a brief text file (INFO.TXT) that describes the directory contents.

3.7 BROWSE Directory Contents and Naming Conventions

The browse directory contains images of INMS summary data and is included only on CO-S-INMS-3-L1A-U-V1.0 data set volumes. Two type of images are included, mass-time spectra and time series data. Each image spans six hours beginning at 0h, 6h, 12h, and 18h. (examples to be added). The image files are all portable network graphics files. The files are named in accordance with the convention in Table 20.

Table 20: Browse Product File Naming Convention Filename format: yyyydddhh_ttt_ vv.PNG
Identifier	Description	Options
yyyydddhh	Start date file	yyy - Year ddd - Day of Year hh - Hour of Day
ttt	Plot type	SPECTRA - mass-time spectra LINE - mass time series
vv	Version number of data	01, 02, ..., etc.

3.7.1 Required Files

Every subdirectory beneath the browse directory contains a file named INFO.TXT which contains a description of the directory contents in ASCII text. Every file in the browse path is described by a PDS label. All labels will be detached, having the same root name as the file they describe with the suffix '.LBL' replacing the suffix of the file name.

3.7.2 BROWSE Directory Contents

The browse directory contains a separated subdirectory for each day. The daily subdirectories are grouped by year into yearly directories. The structure may be seen in Appendix A. The yearly directories will be named for the year, 2004, 2005, and so forth. The daily subdirectories will be named with the ordinal day-of-year, 001, 002,...366. Each daily directory contains eight files, four mass-time spectra and four mass time series. In addition there will be a brief text file (INFO.TXT) that describes the directory contents.

yyyydddhh_LINE_ vv.PNG	Time series browse plots	INMS
yyyydddhh_LINE_ vv.LBL	PDS label for LINE plot file of same base name	PPI

3.8 EXTRAS Directory Contents

The EXTRAS directory contains files that are helpful, but are not required to interpret the INMS data. Files in the EXTRAS directory are exempt from labeling requirements. An EXTRAS directory is included in the CO-S-INMS-3-L1A-U-V1.0 archive. Subdirectories are used to organize the items into groups of related files. The EXTRAS directory will contain two subdirectories, SOFTWARE and CALREPORT. To avoid the requirement of redistributing all physical media data volumes in the event that the EXTRAS contents changes, this directory will be present on only the first physical volume COINMS_3000, and a note to that effect will be placed in the AAREADME file on all physical volumes.

3.8.1 SOFTWARE Directory Contents

The SOFTWARE directory contains a library of IDL routines that may be used to read, manipulate and display the contents of the L1A data files. In addition to the IDL source code files, the directory will contain a user's guide and an HTML help file.

3.8.2 CALREPORT Directory Contents

The calibration report directory in the EXTRAS directory contains the complete report of the pre-launch instrument characterization. The report is in the form of a structured series of files containing data from one characterization test. These files are the source for the initial calibration summary file included in the archive volume. The organization of this directory is shown in Appendix C.

4. ARCHIVE VOLUME FORMAT

This section describes the format of the INMS standard product archive volumes. Data that comprise the INMS standard product archives will be formatted in accordance with Planetary Data System specifications.

4.1 Disk Format

Disk formats for the archive volumes will conform to the PDS standard for the applicable media. At present, the plan is to archive INMS data on DVD-R media.

4.2 File Formats

The following section describes file formats for the kinds of files contained on Archive Volumes. For more information, see the PDS Archive Preparation Guide.

4.2.1 Document File Formats

Document files with the .TXT suffix exist in all directories. They are ASCII files with attached PDS labels. All document files contain variable-length, 80-byte maximum records, with a carriage return character (ASCII 13) in the 79th byte and a line feed character (ASCII 10) in the 80th byte. This allows the files to be read by the MacOS, DOS, Windows, UNIX, OS2, and VMS operating systems.

However, some of the documents in the reference volume contain formatting and figures that cannot be rendered as pure ASCII text. These documents will be provided in formats that support graphics, such as HTML, MS Word, PDF, etc. The PDS requirement that all documentation critical to the understanding of the data set be provided in ASCII text form will be met by the inclusion of CLEAN HTML formatted documents.

4.2.2 Catalog File Formats

Catalog files (suffix .CAT) exist in the Root and Catalog directories. They are formatted in an object-oriented structure consisting of sets of 'keyword = value' declarations. All files are ASCII and conform to the same structure standards (line length, line terminator) as the PDS labels described in the next section.

4.2.3 PDS Label File Formats

All data files in the INMS Standard Product Archive Collection have PDS labels. INMS is producing ASCII comma separated value files for all products. Each file will have an detached label, whose name is identical to the data file name with the .CSV suffix replaced by .LBL.

A PDS label, whether attached or detached from its associated file, provides descriptive information about the associated file. The PDS label is an object-oriented structure consisting of sets of 'keyword = value' declarations. All detached labels contain 80-byte fixed-length records, with a carriage return character (ASCII 13) in the 79th byte and a line feed character (ASCII 10) in the 80th byte. This allows the files to be read by the MacOS, DOS, Windows, UNIX, OS2, and VMS operating systems.

4.2.4 Data File Formats - Comma Separated Value Files

Delimited field, ASCII data files (.CSV suffix) exist in the DATA directories. These files are formatted for direct reading into many database management systems on various computers. In the INMS application of the delimited field format, fields are separated by commas. Records vary in length in bytes but will have a fixed number of fields. Missing data are represented by empty fields. All fields are described by detached PDS labels.

4.3 General Data Product Format

All INMS data products are CSV files that contain a series of homogenous records. Records are delimited by the end-of-line characters, the carriage return character (ASCII 13) followed by the line feed character (ASCII 10). Each file contains one or more lines of column headers. The starting location of the data is indicated in the label by the spreadsheet pointer. The column headers are the same as the field name in the tables below, additional header rows contain the units and strings to use as axis labels in plots. Blank fields indicate that the field is not applicable in the context of the record, the data is not available, is out of nominal range, or is otherwise not suitable for archiving. The following sections describe the content and structure of each of the standard data products within the INMS data sets, as described in Table 12 in Section 2.1.

4.3.1 INMS SCI Data Product Formats

Table 22, below, describes the contents and ranges of the SCI data files. These files contain the contents of the science data packets, converted to dimensional quantities. Each record consists of 9 header items followed by the contents of the telemetry packet.
