Definition of Keywords/Values for SPICE Kernels: ================================================ PDS version identification keyword(s): PDS_VERSION_ID The version of the present PDS standards document -- PDS3 File characteristics keyword(s): RECORD_TYPE Record format of the file; STREAM for all CIDA EDF files because they are variable line length ASCII test files. Product identification keyword(s): DATA_SET_ID "SDU-C/D-CIDA-1-EDF/HK-V1.0" in all CIDA product labels. The fields of this data set ID mean: 'SDU' for Stardust spacecraft; 'C/D' for mission's targets comet Wild 2 and interstellar dust; 'CIDA' for CIDA data identifier; '1' for the CODMAC processing level; 'EDF/HK' for data type identifier; and 'V1.0' for the data set version number. PRODUCT_ID Actual file name. In the example labels, is "T20030424181205A.TAB" and "HK_T19800101_T20030506.TAB". PRODUCT_TYPE Type of EDF product: SPECTRUM, HOUSEKEEPING, FDAQ_CALIBRATION, GLOBAL_VARIABLES, INTERRUPT_VARIABLES, or CONFIGURATION_PARAMETERS. INSTRUMENT_NAME "COMETARY AND INTERSTELLAR DUST ANALYZER" in all CIDA product labels. INSTRUMENT_ID "CIDA" in all CIDA product labels. INSTRUMENT_HOST_NAME "STARDUST" in all CIDA product labels. TARGET_NAME In Spectrum EDF files, set to observation target -- "81P/WILD 2 (1978 A2)" or "INTERSTELLAR PARTICLES" -- or "NON SCIENCE" for EDFs contaning test frames, calibration spectra, or other non-scientific data. In HK EDF files, set to "N/A". START_TIME Data start time in PDS time format (yyyy-mm-ddThh:mm:ss). No quotes are needed. STOP_TIME Data stop time in PDS time format (yyyy-mm-ddThh:mm:ss). SPACECRAFT_CLOCK_START_COUNT Data start time as spacecraft clock. This is treated as a string, and is contained in quotes. Format is "XXXXXXXXX", where XXXXXXXXX are on-board clock integer seconds. SPACECRAFT_CLOCK_STOP_COUNT Data stop time as spacecraft clock in the same format as the start spacecraft clock. PRODUCT_CREATION_TIME Time when the file was created, in PDS time format, yyyy-mm-ddThh:mm:ss. Additional descriptive keywords: INSTRUMENT_MODE_ID "POSITIVE ION MODE" or "NEGATIVE ION MODE" for Spectrum EDF files. Not present in HK EDF file labels. DESCRIPTION Brief description of the data in the file. Object pointer and data object definition keywords: Keywords in this section define TABLE object(s) and their sub-objects and point to the data location within the product. For each of the objects the set of keywords defining it complies with minimum identification requirements.
