This SDDL file defines relation QOARCHIVES. A record is appended to this relation when the OPUS data partitioning process determines the name of the ipppssoot from the science POD file. Any pipeline process that subsequently has trouble processing science data will update the trouble_flag and trbl_process fields. Fields are present to record missing or errored data found in the original POD file via the QAC and other methods. Archive processing updates a number of fields in QOARCHIVES. C*3 Unique 3 character base 36 program identifier for the proposal for which this observation is a part. Used with the obset_id, ob_number, and data_class fields to form the observation 'rootname', which uniquely identifies an observation. C*2 A collection of one or more alignments that are grouped together based on FGS pointing requirements. That is, if multiple alignments can all be executed using the same guide star pair, they are grouped into the same observation set. Part of the OPUS rootname. C*2 Observations are numbered sequentially throughout an observation set and are assigned by sms (base 36 number max. 1295 observations per obset). Part of the OPUS rootname. C*1 Type of data (R real-time, T tape-recorded, etc). C*9 The ipppssoot, where i = instrument code (N - NICMOS O - STIS U - WFPC2 V - HSP W - WFPC1 X - FOC Y - FOS Z - HRS) ppp = program_id ss = obset_id oo = ob_number t = data_class C*16 Time pipeline processing for this dataset. Format is yyyydddHHMMSSsss. C*16 Time pipeline processing completed for this dataset. Format is yyyydddHHMMSSsss. I*4 obsolete field?? C*1 archive flag for file count mismatches C*1 obsolete field?? I*2 obsolete field?? C*1 Set to 'T' if observation sent to 'trouble'. C*6 Name of process that sent observation to 'trouble'. C*9 obsolete field?? C*20 DADS ARCHDATE for EDT archive class. Format is yyyydddHHMMSSsss. I*2 File count for EDT archive class. C*9 obsolete field?? C*20 DADS ARCHDATE for CAL archive class. Format is yyyydddHHMMSSsss. I*2 File count for CAL archive class. C*15 obsolete field?? C*10 obsolete field. C*1 Set to 'T' if missing or errored data was tallied. I*2 count of segments with Reed-Solomon errors. Sets data_problems = 'T' I*2 count of segments with fill added. Sets data_problems = 'T' I*2 count of missing data sections. Sets data_problems = 'T' I*2 count of missing detector readouts. Sets data_problems = 'T' QOARCH_TYPE History of science data processing for a given observation OPUS unique clustered nonclustered nonclustered
