G. Herrera and P. Priest Jet Propulsion Laboratory ==================================================================== INTRODUCTION ==================================================================== This compact disc contains archival data produced during the Jupiter Gravitational Redshift Experiment carried out using the Galileo spacecraft (in cruise to Jupiter) and Earth-based receiving stations of the NASA Deep Space Network (DSN). Each disc in the volume set will contain data from a limited number of Jupiter Gravitational Redshift Experiments. The disc identifiers and the range of dates covered by a data file are VOLUME_ID Dates/Times Covered (inclusive) --------- ----------------------------------------- GORS_0601 1989-1204T22:00:00Z - 1991-1130T23:44:00Z GORS_0602 1992-0209T17:55:00Z - 1992-0802T21:46:45Z GORS_0603 1992-0807T11:09:58Z - 1993-0201T11:24:00Z GORS_0604 1993-0131T22:04:07Z - 1993-0818T02:59:59Z GORS_0605 1993-0622T23:00:00Z - 1993-0930T05:01:13Z GORS_0606 1993-1008T20:33:42Z - 1994-0301T11:00:00Z GORS_0607 1994-0301T11:00:00Z - 1994-0728T11:56:10Z GORS_0608 1994-0728T10:30:00Z - 1994-1020T23:00:07Z GORS_0609 1995-0103T22:00:00Z - 1995-0330T14:48:00Z ==================================================================== VOLUME SET INFORMATION ==================================================================== This disc is one of several which contain Jupiter Gravitational Redshift Experiment raw data. Each archive volume will have the structure illustrated in the diagram below. Not all directories will be included on every disc. In cases where the directory would contain no files, the directory itself will be omitted from the CD-WO volume. Data are arranged in the volume set chronologically. Data files are not repeated within the volume set, although two files may overlap in time during a period in which two DSN stations are tracking the spacecraft simultaneously. root | |- AAREADME.TXT |- ERRATA.TXT |- VOLDESC.CAT | |- CALIB | | | |- CALINFO.TXT Overview of directory | |- LGA1_DL.LBL Galileo's Low Gain Antenna | |- LGA1_DL.TAB pattern information for | |- LGA1_UL.LBL uplink and downlink. | |- LGA1_UL.TAB | |- CATALOG | | | |- CATINFO.TXT Streamlined PDS templates | |- MISSION.CAT for mission, host, | |- INSTHOST.CAT instrument, references, | |- INST.CAT personnel, and data set. | |- REF.CAT | |- PERSON.CAT | |- DATASET.CAT | |- DOCUMENT | | | |- DOCINFO.TXT Overview of directory | |- GLLRSSIS.TXT SIS for this archival data set | |- DESCRIPT.TXT Experiment and data description | |- TRK_2_25.TXT SIS for TDF data type | |- TK_DESCR.TXT NAIF Toolkit organization summary | |- TK_INSTL.TXT NAIF Toolkit installation summary | |- TK_FTP.TXT NAIF Toolkit access instructions | |- HANDBOOK Subdirectory containing Radio | | Science Handbook | |- GEOMETRY | | | |- GEOMINFO.TXT | |- SyymmddA.XSP | |- SyymmddA.LBL | |- INDEX | | | |- INDXINFO.TXT | |- INDEX.LBL | |- INDEX.TAB | |- CUMINDEX.LBL | |- CUMINDEX.TAB | |- ODR Data directories |- TDF ==================================================================== ERRATA ==================================================================== A cumulative list of errors and changes is maintained in the file ERRATA.TXT at the root level of each volume. Higher volume numbers will show errors in this disc that were discovered after it was produced. ==================================================================== DISC FORMAT ==================================================================== The disc is organized according to the PDS standard for "one data set, many volumes." This file (AAREADME.TXT), a PDS volume object definition (VOLDESC.CAT), and the listing of errors and changes (ERRATA.TXT) are included at the root level. The following directories of descriptive material are also at the root level: CALIB contains tables of low-gain antenna pattern measurements. CATALOG contains descriptive files for cataloging each of the data types included in this disc. DOCUMENT contains a plain text Software Interface Specification (SIS) for each data type, if available, plus other documentation. GEOMETRY contains NAIF SPK, CK, and SCLK files giving spacecraft and planetary ephemerides during the observation period and attitude information for reconstructing the spacecraft antenna pointing. INDEX contains index information on each of the data files included in this disc; it also includes a cumulative index to all files in this volume set. The remaining directories at the root level contain data files and detached PDS labels. ==================================================================== FILE FORMAT ==================================================================== All data files on the disc are accompanied by detached PDS labels, which describe their contents. PDS TEXT objects include attached labels. Minimal labels were used to facilitate transfer of the data to an archive; construction of full labels with object definitions would have added significantly to the development time, possibly putting the total effort in jeopardy. Detached labels were chosen over attached labels for simplicity of implementation. Labels have the same file name as the primary data file except for the suffix ".LBL". Detailed documentation on file structure is available in Software Interface Specifications in the DOCUMENT directory. Text files, including data files of ASCII text and all labels (*.LBL files) and tables (*.TAB files), are delimited by carriage- return (ASCII 13) line-feed (ASCII 10) pairs at the end of each line. ==================================================================== ACKNOWLEDGMENTS ==================================================================== Jim Taylor provided the Galileo Low-Gain Antenna pattern information. Richard Simpson is responsible for a major portion of the documentation, and he provided guidance and PDS information during the creation of this archive. He also reviewed proposed archival products. ==================================================================== DISCLAIMER ==================================================================== Although considerable care has gone into making this volume set, errors are both possible and likely. Users of the data are advised to exercise the same caution as they would when dealing with any other unknown data set. Reports of errors or difficulties would be appreciated. Please contact one of the persons listed below. ==================================================================== COGNIZANT PERSONNEL ==================================================================== The people most directly responsible for construction and release of this volume set are Randy Herrera and Patricia Priest. Randy Herrera is the Science Coordinator for Galileo Radio Science, and both are members of the Radio Science Support Team. The Principle Investigator for the Galileo Jupiter Gravitational Redshift Experiment is John Anderson.
