Simpson Stanford University ==================================================================== INTRODUCTION ==================================================================== This compact disc contains archival data produced during bistatic radar observations carried out using the Magellan spacecraft (orbiting the Moon) and Earth-based receiving stations of the NASA Deep Space Network. Each disc in the volume set will contain data from a limited number of bistatic radar observations. The disc identifiers and the range of "applicable start times" are VOLUME_ID Dates/Times Covered (inclusive) --------- ----------------------------------------- CL_2001 1994-04-09T17:48:45 - 1994-04-09T19:24:44 CL_2002 1994-04-09T19:24:45 - 1994-04-09T23:48:54 CL_2003 1994-04-09T23:48:55 - 1994-04-10T01:24:54 CL_2004 1994-04-10T01:24:55 - 1994-04-10T05:22:21 CL_2005 1994-04-10T05:22:22 - 1994-04-10T06:46:54 CL_2006 1994-04-10T08:52:22 - 1994-04-10T10:28:23 CL_2007 1994-04-10T10:28:24 - 1994-04-23T09:23:07 CL_2008 1994-04-23T09:23:08 - 1994-04-23T10:46:01 CL_2009 1994-04-23T18:15:14 - 1994-04-23T19:39:31 CL_2010 1994-04-23T19:39:32 - 1994-04-23T21:15:31 CL_2011 1994-04-23T21:15:32 - 1994-04-23T22:51:31 CL_2012 1994-04-23T22:51:32 - 1994-04-24T00:27:31 CL_2013 1994-04-24T00:27:32 - 1994-04-24T01:54:40 ==================================================================== VOLUME SET INFORMATION ==================================================================== This disc is one of several which contain Clementine bistatic radar raw data from lunar observations. Each archive volume will have the structure illustrated in the diagram below. Not all directories will be included on every disc; for example, only the first volume has TDF data. In cases where the directory would contain no files, the directory itself will be omitted from the CD-WO volume. Data are grouped in the volume set according to the "applicable start time" of the data in each file. Data files are not repeated within the volume set, so a single file that covers several observing intervals will appear only on the first disc for which it would apply. root | |- AAREADME.TXT |- ERRATA.TXT |- VOLDESC.CAT | |- CALIB | | | |- CALINFO.TXT Overview of directory | |- NOTESddd.TXT Notes from day-of-year ddd | |- QHGA_L_Q.LBL Antenna patterns and accompanying | |- QHGA_L_Q.TAB detached PDS labels | |- QHGA_C_Q.LBL | |- QHGA_C_Q.TAB | |- QHGA_C_2.LBL | |- QHGA_C_2.TAB | |- XPNDRnnn.TXT Transponder data, revolution nnn | |- 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 | |- ARC_SIS.TXT SIS for this archival data set | |- DESCRIPT.TXT Experiment and data description | |- LMC.TXT Description of LMC data type | |- RSC11_11.TXT SIS for ODR data type | |- TK_DESCR.TXT NAIF Toolkit organization summary | |- TK_INSTL.TXT NAIF Toolkit installation summary | |- TK_FTP.TXT NAIF Toolkit access instructions | |- TRK_2_25.TXT SIS for TDF data type | |- GEOMETRY | | | |- GEOMINFO.TXT Overview of directory | |- CKyyddd.TCK Transfer format CK file for | | year yy and day ddd | |- DSPSE002.TSC Transfer format SCLK file | |- SPKyyddd.TSP Transfer format SPK file for | | year yy and day ddd | |- *.LBL Detached PDS labels | |- INDEX | | | |- INDXINFO.TXT | |- INDEX.LBL | |- INDEX.TAB | |- CUMINDEX.LBL | |- CUMINDEX.TAB | |- ODR Data directories |- LMC |- 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 high-gain antenna pattern measurements, notes from real-time observations, and engineering data from the on-board radio transponder. 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 "minimal" PDS labels, which describe their contents. PDS TEXT objects include attached labels. All PDS labels include an SFDU label in the first record. 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 ==================================================================== Descriptions of the Clementine spacecraft, and especially its radio system, were provided by Chris Lichtenberg of the Clementine Project, who was also the experiment Principal Investigator and oversaw spacecraft operations during experiment periods. Antenna pattern measurements were provided by Fred Domer and Howard Taylor of the Clementine Project. Sami Asmar provided the interface with the NASA Deep Space Network during the experiment period. The JPL Radio Science Support Team provided open-loop (ODR) data from the experiment. Chuck Acton and Mike Spencer provided NAIF files (CK and SCLK files); Hester Neilan provided an updated copy of the NAIF Toolkit. Clementine SPK files were provided by Frank Lemoine of Goddard Space Flight Center. Gail Woodward and Ruth Monarrez served as interfaces with the Planetary Data System, reviewing proposed archival products as the need arose. Eric Eliason of the PDS Imaging Node also reviewed catalog (descriptive) files. ==================================================================== 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 person most directly responsible for construction and release of this volume set is Richard Simpson, Experiment Engineer for the Mars Global Surveyor Radio Science Team and Radio Science Advisor to the Planetary Data System. Although many people contributed to the volume set, any faults in the product are his alone. The Team Leader for the Mars Global Surveyor Radio Science Team and for this archiving activity is G.
