Every effort has been made to ensure that the data and documentation are of the best possible quality. However, mistakes are inevitable. The PPI Node of the PDS will maintain an online list of ERRATA where errors and updates are documented. Should any user of this product find an error on this volume, please report the error to the PPI Node so that the finding can be made public. All users are encouraged to verify the "correctness" of the data prior to submitting any publications or other work based on these data. Users of these data are encouraged to acknowledge both the PDS and the principal investigators of the instruments whose data are used in analysis in all publications. ======================================================================== IMPORTANT INFORMATION ABOUT THIS VOLUME -- READ THIS FIRST! ======================================================================== This volume contains includes all RPWS telemetry data for the entire Cassini mission. New data will be added to the volume as they become available. KEY THINGS TO KNOW IN USING DATA ON THIS VOLUME: All data files are stored under the DATA top-level directory and are organized by spacecraft event time. The DATA directory branches off into: * ANCILLARY, containing instrument mode and sequence information * RPWS_RAW_COMPLETE, containing complete instrument telemetry packets The data are stored in binary files with labels and format descriptions included as separate files. PDS labels are contained in associated "*.LBL" text files in the same directories as the data files and shared descriptions of many of the data structures are stored in "*.FMT" files in the LABEL top-level directory. General information for this volume is provided in PDS catalog files located in the CATALOG directory. The data set is documented in: * CO_RAW_DS.CAT, describing RPWS_RAW_COMPLETE Other PDS catalog files include: * CO_INST_HOST.CAT, describing the Cassini Orbiter spacecraft * CO_MISSION.CAT, describing the Cassini-Huygens mission * CO_RPWS_PERSON.CAT, listing RPWS and PDS personnel * CO_RPWS_REF.CAT, listing useful literature references * CO_RPWS_INST.CAT, describing the RPWS instrument ======================================================================= Related PDS Products ======================================================================= This volume is part of a set of 5 volumes containing RPWS Standard Products from the full Cassini mission. These include the following volumes: * CORPWS_9001, contains the raw complete (telemetry packets) data set * CORPWS_9002, contains the resampled key parameters data set (summary spectral information in units of spectral density) * CORPWS_9003, contains the calibrated full-resolution low rate data set (all spectral information in units of spectral density) * CORPWS_9004, contains the edited full resolution waveform data set * CORPWS_9005, contains the edited full resolution wideband data set Planned for archive later are higher level data products from the Radio and Plasma Wave Science investigation including polarization and direction-finding measurements of planetary radio emissions, electron density measurements via a number of techniques including the use of a Langmuir Probe and sounder, and wave-normal analysis results of plasma waves. Another related PDS product is the Cassini Magnetosphere and Plasma Science Key Parameter data set which includes the RPWS Key Parameter data set included herein along with similar products from the Cassini Magnetometer, Magnetospheric Imaging Instrument, and Cassini Plasma Spectrometer Subsystem. ======================================================================== Volume Format Information ======================================================================== The volume is organized into a hierarchical directory structure. The volume is formatted according to a combination of ISO 9660, UDF, Rock Ridge (UNIX), and Joliet (Microsoft) standards in order to accommodate users on a wide variety of platforms. This volume does not contain any Extended Attribute Records (XAR). Thus, VMS users may have some problems accessing files on this volume. ======================================================================== File Formats ======================================================================== The data files on this volume are binary files. All data files are described by detached PDS labels. A detached label file has the same name as the data file that it describes, but with the extension .LBL. For example, the file T1999227_HFR0.DAT is accompanied by the detached label file T1999227_HFR0.LBL in the same directory. File names within this archive comply with the "27.3" convention for compliance with ISO 9660 Level 2 interchange requirements. All documents, detached PDS labels, and HTML files are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of the record. This allows the files to be read by MacOS, DOS, Windows, UNIX, and VMS operating systems. UNIX system users may see an unnecessary carriage return character (^M) at the end of each line. Mac users may see an unnecessary line feed character (^J) at the start of each line. The document, PDS label, and ASCII table files on this volume can be viewed with a Web browser. Note that to view these files, the browser may need to be configured to recognize files with extensions of .CAT, .LBL, and .TAB as text files. Users with Web browsers also can navigate the disk via the HTML file AAREADME.HTM in the disk's root directory and the HTML files in the BROWSE directory. PDS labels are object-oriented. The object to which the label refers (e.g., SERIES, TABLE, etc.) is denoted by a statement of the form: ^object = location in which the caret character (^, also called a pointer in this context) indicates that the object starts at the given location. For an object in the same file as the label, the location is an integer representing the starting record number or byte of the object (the first record/byte in the file is 1). For an object located outside the label file, the location denotes the name of the file containing the object, along with the starting record or byte number. For example: ^SPECTRAL_DENSITY_TABLE = ("T1999227_HFR0.DAT", 4) indicates that the SPECTRAL_DENSITY_TABLE object begins at record 4 of the file T1999227_HFR0.DAT, in the same directory as the detached label file. Below is a list of the possible formats that use the ^object keyword. ^object = n ^object = n ^object = ("filename.ext",n) ^object = ("filename.ext",n) where n is the starting record or byte number of the object, counting from the beginning of the file (record 1, byte 1); default is record number. indicates that number given is in units of bytes. filename upper-case file name. ext upper-case file extension. In cases where many files of the same format or structure are present, the structure description component is detached from the primary label. This minimizes repeating information which does not vary from file to file. In these cases, a format file (.FMT) contains the file structure information and the base label (.LBL) describes the parameters which generally do vary from file to file (number of records, file name, start/stop time, etc.). When a format file is used within the PDS label, the syntax is: ^STRUCTURE = filename Example: ^STRUCTURE = "LRFULL_TABLE.FMT" Syntactically, the contents of the format file can be inserted directly into the base label such that the entire file contents replace the single line ^STRUCTURE = filename. Note that these shared format files are collected in the top-level LABEL directory on this volume. ======================================================================== Errata ======================================================================== There is a file called ERRATA.TXT found at the root level of this volume which contains a list of known deficiencies or caveats associated with data on this volume at the time it was published.
