Volume PV05_0013 Pioneer Venus Orbiter - Venus Orbital Operations CD-ROM Supplementary Experimenter Data Records (SEDR) Orbits 4701-5055 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 Magnetometer 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. Brief Disk Description This CD-ROM contains data for orbits 4701-5055 covering the time period from 1991-10-19T16:00:00.000Z to 1992-10-08T18:14:00.000Z. There is no data for orbits 4927-4954 due to superior conjunction. There is no data for orbit 4860, 4901-4908, 4956-4959, and 4981-4982 though the reason for these data gaps are unclear. All data files are stored in the "DATA" branch of the directory tree. Data are stored in IBM binary/EBCDC format (*.DAT). Each file has a corresponding PDS label file, *.LBL. Software to convert binary data to ASCII can be found in the SOFTWARE directory. When the UCLA magnetometer team corrected the pulse times, they either corrected or inserted the following fields as appropriate: msec_of_Fs, msec_of_Rip and nearest_real_sun_pulse. The values for the other fields in such records were set to zero. Note: due to a bug in the early version of the program, some orbits contain invalid values in some of the corrected or inserted records. These values should be ignored. A list of the files and record numbers that contain this error are available in the file /DATA/AANOMOLY.TXT. The list, however, is not exhaustive and while this error is not known to have occurred for any of the orbits included on this volume the user should exercise caution when using this data. Users of this disk should read the INFO.TXT file located in the DATA directory which explains where each type of data is located, as well as the INFO.TXT files located in each data directory which describe the data in that directory. Novice users can ignore all directories and files except for those mentioned in this brief description. ============================================================================== Documents ============================================================================== This volume contains a document version of the Mission template. This document is supplemented by numerous scanned figures from the NASA Special publication SP-518, 'Pioneering Venus: A Planet Unveiled' by Fimmel et al. Figures are provided in either GIF format. This new version of the mission and host template is provided to add completeness to the archive of these large datasets. They contain information about the mission and the spacecraft that would be difficult to capture with text alone. However, the information is still incomplete. Users interested in the mission history or the details of the spacecraft configuration or operation should obtain a copy of NASA SP-518. There is also a document version of the Pioneer Venus Project Specification PC-456.O4 Pioneer Venus: Data User Requirements for Supplementary Experimenter Data Records. ============================================================================== Volume Set Information ============================================================================== This CD-ROM is the thirteenth disk of the PV05_xxxx series. This volume set contains an exact copy of the original SEDR data tapes provided to the Magnetometer instrument team. These original data tapes contained six different files all stored in IBM binary/EBCDC format. These files are 1) a logistics or tape header file, 2) a spacecraft attitude file, 3) an ephemeris file, 4) a pulse time file, 5) a selected roll reference file, and 6) a spin period file. In addition to these original 6 files, the magnetometer team has included their "corrected pulse time" file. With this one exception, no effort has been made to process or change in any way the original SEDR data as provided by the project. The Electric Field Detector data is used to "correct" the pulse times. OEFD detects a signal that is not due to plasma waves that is synchronized with the sun. The phase of this signal is calculated at the spin period relative to the solar direction, using the pulse times provided by the project. If the phase is not in the range expected or if the phase is drifting there is a problem with the pulse times. The 5.4 kHz channel is used because of the generally low level of ambient (natural) signal at this frequency and because the sun induced spin signal is well defined at this frequency. The complete volume set will include orbits 1-5055 (1978-12-05 to 1992-10-07). As the last disk of the series, this CD contains all catalog templates, documentation, and software pertinent to the entire volume series. ============================================================================== Errata ============================================================================== There is a file called ERRATA.TXT found at the root level of this volume which contains a list of changes and errors if there are any at the time this CD was published. This is a list of cumulative changes made to any PVO SEDR CD-ROM (volume set PV05) created by this production date. Any changes or errors that were found on any PV05 CD-ROM after the production of this volume can be found via anonymous-ftp at pdsppi.igpp.ucla.edu. 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/PV05), and transfer the file ERRATA.TXT (get ERRATA.TXT). Changes can also be found through our web site at http://www.igpp.ucla.edu/igpp/ditdos.exe through the data access system. ============================================================================== File Formats ============================================================================== All files on this disk are described by detached version 3.0 PDS labels. 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 directories contain multiple data files all with an identical structure. There are two ASCII text format files which describe the physical structure of the data files (header and data areas). These format files are then pointed to by all of the labels. Both the label files and the format files (*.FMT) are all located in the same directory as the data they describe. ============================================================================== 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. ============================================================================== Volume Contents and Structure ============================================================================== This section describes the volume structure and naming conventions. Below is a tree diagram of the CD-ROM, followed by a description of the directory function and key files in each directory.
