Volume PV04_0033 Pioneer Venus Orbiter - Venus Orbital Operations CDROM Radio Science Experiment Original Data Records (ODR) Occultation Season 13 - disk 5 Pass 4168-4178 Planetary Plasma Interactions Node of the Planetary Data System ============================================================================== Introduction ============================================================================== This disk contains Venus Orbital Operations data submitted to the Planetary Data System (PDS) by PVO Radio Science Experiment project investigators. Every effort has been made to assure that the data are of the best quality available. However, the PDS and the Planetary Plasma Interactions (PPI) Node in particular, assume no liability for this disk or its contents. All users are encouraged to verify the "correctness" of the data prior to submitting any publications or other work based on these data. This CD-ROM contains data for the middle of occultation season 13 (passes 4108-4178) which covers passes 4168-4178 covering the time period between 1989-10-16T03:07:01.000Z through 1989-10-26T03:34:01.000Z. ============================================================================== Volume Set Information ============================================================================== This CD-ROM is the thirty-third disk of the PV04_xxxx series. It is the thirty-second disk in the series which contains actual ODR data files. The first disk in this series contains navigation (NAVIO) data, DSN logs, and other ancillary information necessary to process these data. All of the ancillary files were packaged on a single CD-ROM at the request of the Radio Science investigators. If this user of this disk needs to process these data, please refer to volume PV04_0000 for the NAVIO and other related files. All ODR software provided by the Radio Science team for archival is contained on PV04_0000. Occultation Season 14 - volumes PV04_0001 - PV04_0003 Occultation Season 11 - volumes PV04_0004 - PV04_0013 Occultation Season 10 - volumes PV04_0014 - PV04_0024 Occultation Season 12 - volumes PV04_0024 - PV04_0028 Occultation Season 13 - volumes PV04_0029 - PV04_0033 ============================================================================== Errata ============================================================================== There is a file called ERRATA.TXT found at the root level of this volume which contains a list of changes and errors. This is a list of cumulative changes made to any PVO ODR CD (volume set PV04) created by this production date. Any changes or errors that were found to any PV04 CD after the production of this volume can be found via anonymous-ftp at srvsun.igpp.ucla.edu (ftp 128.97.68.55). The account name is anonymous and the password should be your e-mail address (it's nice to leave an audit trail). Change to the PDS errata directory (cd pds/ERRATA/PV04), and transfer the file ERRATA.TXT (get ERRATA.TXT). ============================================================================== Disk Format ============================================================================== The disk is organized into a hierarchical directory structure which the PPI Node hopes will be both intuitive for the user as well as easy to use. The disk is formatted according to both ISO 9660 and POSIX (Unix) standards in order to accommodate users on a wide variety of platforms. All of the label, table, and text files are ascii with CR/LF (VAX / IBM-PC) format. The basic organization of the disk is as follows: CATALOG CATALOG.CAT, containing instrument, dataset, and data quality templates can be found on volume PV04_0000. MANAGE contains data management information for the DITDOS software. Users do not need to make use of any of these files directly, however, the software which allows DITDOS to extract and reformat data files needs to have this information. INDEX contains a cumulative index table which describes the location of all files on the disk for users who do not wish to make use of the DITDOS software. DATA contains all data in a branching tree structure of sub-directories. Data files are given a pass filename of the form "PMCXXXX.ODR" where XXXX is the tape sequence number. DOCUMENT contains textual material that describes instrument and dataset. This can include references to science papers, or the actual papers. ============================================================================== File Format ============================================================================== All files on this disk are described by detached version 3.0 PDS labels. Version 3.0 of the PDS label does not support detached TEXT file labels, however, TEXT file labels are detached on this disk. PDS labels are identified by a .LBL file name extension. There is one label file for each text and data file contained on this disk and the file name prefix is the same as the file the label describes. The data on this disk are identified with PDS short labels. If the dataset is stored as multiple files (as most of them are), there will be a single ASCII text format file which describes the physical structure of the data. This format file is then pointed to by all of the labels. Both the label files and the format file (ODR_FMT.TXT) are all grouped in the same directories as the data they describe. ============================================================================== Volume Contents ============================================================================== This section describes the volume structure and naming conventions. This basic disk structure is described in the disk format section. Here we describe the directory structure of this volume and the names/contents of the key files in each directory. Catalog Directory: This disk does not contain any catalog information. All catalog templates for the PVO-ODR dataset are contained on volume PV04_0000. key files: CATINFO.TXT - explains where to find catalog information. Data Directory: The data files, labels, and format description document are contained in the DATA subdirectory. Data files have the name PMCxxxx.ODR where the "xxxx" is the tape sequence number of the file. key files: INFO.TXT - explains the directory contents ODR_FMT.TXT - described the structure of the ODR data files PMCxxxx.ODR - ODR data file sequences number xxxx for occultation season 13 PMCxxxx.LBL - PDS label for data file PMCxxxx.ODR Document Directory: The document directory contains an electronically scanned version of document RSC 11-10a which describes to structure of the ODR tapes (files) for occultation season 13. The document is stored in two different forms: 1) raw ascii text which can be viewed on a computer screen but does not contain any figures, and 2) the raw scanned image bit maps in TIF compressed 3 format which can be loaded into many different word processors such as WordPerfect, Adobe, etc. and then sent to a printer. key files: DOCINFO.TXT - describes the directory contents and software available for TIFF file conversion and display. PMC.ASC - ascii text version of RSC 11-10a PMCxx.TIF - scanned image of page xx of RSC 11-10a in TIFF compressed 3 format. PMC.LBL - PDS document label describing the PMC document and it forms. Index Directory: The index directory contains a cumulative index (CUM_INDX.TAB) which contains an index of all files in the ODR volume series (PV04_xxxx) and a local index (INDEX.TAB) which points to every file on this volume. The index files are ascii tables which can be easily loaded into a database or spreadsheet program. The index files are described by a detached PDS labels. key files: INDXINFO.TXT - explains the directory contents. CUM_INDX.TAB - cumulative index for all PV04_xxxx volumes. INDEX.TAB - index file which gives the location and file information for each file on this volume (PV04_0033). Manage Directory: This directory contains several IGPP flatfiles which are used by some of the software in the software directory. These files are not intended for direct use by a user so there are no PDS labels. key files: No user files in this directory! ============================================================================== Driver and Hardware Information ============================================================================== This disk has been formatted according to the ISO standard for CDROM production (9660) with level 1 compliance. Any system which complies with this standard (all of them should) should be able to access this disk.

He was the PPI Node Data Administrator at the time this disk was created and he understands as much about the disk structure and data organization as anyone. The construction of the PDS labels and templates was done by Ms. Eva Fried of the PPI Node and Ms. Sue Hess and Ms. Ruth Monarrez of the Central Node at JPL. Mike Martin of JPL has helped to insure this disk conforms to accepted PDS standards.
