PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 1998-05-01 NOTE = "INFO.TXT describes the contents of this directory." END_OBJECT = TEXT END This directory contains Voyager 1 Jupiter encounter ephemeris data in Heliographic coordinates covering the period 1979-02-26 to 1979-03-24. Two versions covering the same time period, but containing slightly different data, are provided. One version was generated by the Voyager MAG team from Voyager 1 SEDR and the other by the PDS/PPI node using Voyager 1 SPICE. The data are stored as 8 ASCII tables, each covering about a week of data. These files are named according to the convention [source]ddd.TAB where [source] identifies the source from which the data were generated (either 'SEDR' or 'SPICE') and ddd = the day of year of 1979 on which data coverage begins. Each data file has a PDS label file (.LBL) which describes the properties of the data. There are also two separate format files, SEDRHG.FMT and SPICEHG.FMT, which describe the record structure of the SEDR and SPICE ephemeris files respectively. Please refer to the file DATASET.TXT for a more detailed description of data set contents. The geometry information provided on this volume only includes the SPICE SPK file (containing spacecraft and target body ephemeris). As of the date of publication of this volume, no spacecraft orientation data were available. The PDS/NAIF node is in the process of restoring spacecraft orientation information for the SPICE pointing kernel (C-kernel). NAIF plans to make this kernel available in a future archive. For information regard the availability of the Voyager 1 SPICE C-kernel, please contact Chuck Acton (INTERNET: cacton@spice.jpl.nasa.gov, DECNET: NAIF::CACTON, PHONE: (818) 354-3869) or check the PDS website's link to the NAIF node for current NAIF contact information. The PDS/PPI node is in the process of preparing a data set that will contain the spacecraft orientation information relevant to PRA and other Voyager instruments for which spacecraft orientation is important. This data set will be archived in a future volume. For information regarding the availability of this data set, please contact PDS Operator at the PDS/PPI node (INTERNET: pds_operator@igpp.ucla.edu, PHONE: (310) 206-6073). Additional information associated with this data set is available in the following files: file contents /CATALOG/EPHHGDS.CAT data set description (description duplicated in DATASET.TXT) /CATALOG/PERSON.CAT personnel information /------------------------\ | SEDR FILE FORMAT | \------------------------/ Columns in SEDR generated files: ===================================================== name type description ----------------------------------------------------- time a24 time in the format yyyy-mm-ddThh:mm:ss.sssZ m65536 i5 spacecraft clock mod 65536 mod60 i2 spacecraft clock mod 60 fds_line i1 spacecraft clock fds line sc_x 1pe15.8 heliocentric x (AU) sc_y 1pe15.8 heliocentric y (AU) sc_z 1pe15.8 heliocentric z (AU) vel_x 1pe15.8 heliocentric x velocity (km/s) vel_y 1pe15.8 heliocentric y velocity (km/s) vel_z 1pe15.8 heliocentric z velocity (km/s) sc_r 1pe15.8 Sun-spacecraft range increasing away from the Sun (AU) sc_lat 1pe15.8 spacecraft solar (heliocentric) latitude (degrees) sc_lon 1pe15.8 spacecraft solar longitude (degrees) SolEquator_to_HG 3x3 solar equatorial to heliographic coordinates rotation matrix HG_to_EarthOrbTrue 3x3 heliographic to earth orbit true coordinates rotation matrix Spacecraft_to_HG 3x3 payload (spacecraft) to heliographic coordinates rotation matrix /-------------------------\ | SPICE FILE FORMAT | \-------------------------/ Columns in SPICE generated files: ===================================================== name type description ----------------------------------------------------- time a24 time in the format yyyy-mm-ddThh:mm:ss.sssZ R f10.5 Sun-spacecraft distance (AU) LAT f8.3 spacecraft solar (heliocentric) latitude (degrees) LON f8.3 spacecraft solar longitude (degrees) LocTime f8.3 spacecraft local time (hours) /-------------------------\ | D A T A F I L E S | \-------------------------/ SEDR Data Files (SEDR*.TAB) ============================================================================== Name Records Cols Len Start Stop ------------------------------------------------------------------------------ SEDR057 6046 13 613 1979-02-26T00:00:35.897Z 1979-03-04T23:58:11.925Z SEDR064 6071 13 613 1979-03-05T00:00:35.925Z 1979-03-11T23:59:08.059Z SEDR071 6065 13 613 1979-03-12T00:00:44.059Z 1979-03-18T23:58:20.235Z SEDR078 5303 13 613 1979-03-19T00:00:44.236Z 1979-03-24T22:47:56.304Z SPICE Data Files (SPICE*.TAB) ============================================================================== Name Records Cols Len Start Stop ------------------------------------------------------------------------------ SPICE057 12093 5 64 1979-02-26T00:00:35.897Z 1979-03-04T23:59:47.925Z SPICE064 12142 5 64 1979-03-05T00:00:35.925Z 1979-03-11T23:59:56.059Z SPICE071 12131 5 64 1979-03-12T00:00:44.059Z 1979-03-18T23:59:56.236Z SPICE078 10607 5 64 1979-03-19T00:00:44.236Z 1979-03-24T22:49:32.304Z /------------------------\ | SEDR STATISTICS | \------------------------/ Note that statistics for coordinate rotation matrix elements have been omitted. ============================================================================== MAX/MIN Statistics for: SEDR057 ------------------------------------------------------------------------------ :::::::::::::: SEDR057.stats :::::::::::::: /=====================================================================\ | D A T A F L O W S T A T I S T I C S | \=====================================================================/ Number of columns in data flow: 40 --------- Aggregate Statistics ---------- Total number of records: 6046 /======================================================================\ | COLUMN | MINIMUM | MAXIMUM | AVERAGE | #
