Introduction This tape volume contains IRIS full resolution spectra data and associated pointing and geometric information for both the Voyager 1 and Voyager 2 Jupiter encounters. Also included in this volume is calibration information for the IRIS instrument on each spacecraft, PDS catalog information describing the IRIS instrument and Jupiter data set, and PDS labels and record structure information for the data set. 2. Tape Contents This tape contains the following files, created with the VAX/VMS Backup utility as a single save-set. The following directories/files are included: Directory/Filename Description ----------------------------- ---------------------------------------- VOLDESC.CAT PDS Volume Object description. AAREADME.TXT This file. [CATALOG]JUP_DS.CAT PDS catalog object describing the VGR IRIS Jupiter data set. [CATALOG]VG1_IRIS.CAT PDS catalog object describing the VGR 1 IRIS instrument. [CATALOG]VG2_IRIS.CAT PDS catalog object describing the VGR 2 IRIS instrument. [CALIB]VG1JNESR.DAT Voyager 1 interferometer noise equivalent spectral radience data file. [CALIB]VG2JNESR.DAT Voyager 2 interferometer noise equivalent spectral radience data file. [CALIB]VG1PREJT.LBL PDS label for Voyager 1 target plate calibration for radiometer pre-Jupiter encounter period. [CALIB]VG1PREJT.DAT Voyager 1 target plate calibration data for pre-Jupiter encounter period. [CALIB]VG2PREJT.LBL PDS label for Voyager 2 target plate calibration for radiometer pre-Jupiter encounter period. [CALIB]VG2PREJT.DAT Voyager 2 target plate calibration data for pre-Jupiter encounter period. [CALIB]VG1PSTJT.LBL PDS label for Voyager 1 target plate calibration for radiometer post-Jupiter encounter period. [CALIB]VG1PSTJT.DAT Voyager 1 target plate calibration data for post-Jupiter encounter period. [CALIB]VG2PSTJT.LBL PDS label for Voyager 2 target plate calibration for radiometer post-Jupiter encounter period. [CALIB]VG2PSTJT.DAT Voyager 2 target plate calibration data for post-Jupiter encounter period. [LABEL]IRISHEDR.FMT PDS label format file describing header fields that preceed each IRIS spectral record. [LABEL]IRISTRGP.FMT PDS label format file describing fields in target plate calibration data files. [DATA]VG1_JUP.LBL PDS label describing VG1 IRIS Jupiter data file and associated NESR file. [DATA]VG1_JUP.DAT VG1 IRIS Jupiter data, approximately 43 MB. The data are ordered by FDS count. [DATA]VG2_JUP.LBL PDS label describing VG2 IRIS Jupiter data file and associated NESR file. [DATA]VG2_JUP.DAT VG2 IRIS Jupiter data, approximately 55 MB. The data are ordered by FDS count. 3. File Format Most files on this tape have a label encoded in the Object Description Language (ODL) developed by the Planetary Data System (PDS). An ODL label is readable by both humans and computers. It provides a formal description of the format and content of a file. For some files the ODL label appears at the beginning of the file (as is the case for this file). Binary data files provided on this tape are described by detached ODL labels. The detached labels end in a .lbl extension and the associated data file ends in a .dat extension. PDS label formats and documentation conform to standards as defined by the Planetary Data System Standards Reference (JPL D-7669, Part 2, November 1992, Version 3.0) and the Planetary Science Data Dictionary (JPL D-7116, November 1992, Rev. C) with the following exceptions. Data product labels for the products were approved prior to the release of the Version 3.0 Standards Reference, so do not strictly conform to the Data Product Label standard in Ch. 5 of the PDS Standards Reference, Version 3.0. In particular, the Standard Formatted Data Unit (SFDU) standard from Chapter 17 of the Planetary Data System Data Preparation Workbook - Volume 2, Standards, May 3, 1991, Version 2.0 is used. 4. On-line Analysis and Ordering Capabilities Portions of this data set are available on-line through the Planetary Atmospheres Node Data Analysis (PANDA) system at the PDS Atmospheres node, and a variety of data analysis services are available. In addition, subsets of this data set meeting various user-supplied selection criteria are also available for electronic delivery. 5.
