07/03/03 48821 CTB Converted to XML format This relation is used to provide DADS and OPUS with the SMS_ID for any observation in the support schedule. It can be used to list all observations and association products for a particular SMS_ID. It contains a status field to identify observation or product archive success or unavailability. It contains eight OPUS tracking fields not used by DADS. C3 BASE_36 When a proposal is accepted into the PMDB by SPSS it must be assigned a unique 3 character base 36 program identifier. This is done by the PMDB/ACCEPT_PROP command. Is is used for identification of proposals by spacecraft and OPUS software. It is also used in the OPUS and DADS rootname for all archived science data files. Because of flight design software, program_id must be three characters. C2 BASE_36 An observation set is 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. C3 BASE_36 Observations are numbered sequentially throughout an observation set and are assigned by SMS/Gen. An ob_number is _NOT_ the same as an obset_ID. The third character is only used for association products. C9 C1 The condition or availability for archiving is indicated by a status code with the following definition: U - Unexecuted - the initial condition for exposures or products that will be archived independently of associations. M - Member - the initial condition for exposures that are only archived within an association product. N - Not available - set by operations to indicate exposures or products that cannot be generated. E - Executed and archived successfully. C1 One character identifier for the instrument used for the science observation. The relation between this value and the names in qobservation.si_id are: 1 = 1 2 = 2 3 = 3 J = ACS N = NIC O = STIS U = WFII V = HSP W = WFPC X = FOC Y = FOS Z = HRS C1 Flags observation as a target acquisition. Y - The qobservation.target_acqmode field is 01 or 02. This observation is a target acquisition. C1 Flags this observation as real time (mode 1) target acq. Y - The qobservation.target_acqmode field is 01. This observation is a mode 1 (real time) target acquisition image. C1 OPUS pipeline has created a PDQ file for this observation. The value of this column is an alphanumeric code that indicates the status, real or inferred, of the PDQ file for the observation. C1 OMS pipeline has successfully achived an observation log for this observation. X - The data assessment software has validated existence of the OMS observation log for this observation in DADS. C1 OPUS staff has checked for existence of real time information for this observation. X - The OPUS staff has run RTI_CHECK software for this observation. C1 An OCX file has been appended to the PDQ file. The value of this column is an alphanumeric code that indicates that the data assessment software has located an OCX file (and the type of file) for this observation and has appended it to the PDQ file. C1 This observation has been assessed for procedural quality. The value of this column is an alphanumeric code that summarizes the essentials of the assessment process. C1 Archive status of the procedureal data quality file(s). The value of this column is an alphanumeric code that indicates the archive status of the PDQ (and optionally the OCX) file of this observation. C17 This field (format: yyyy.ddd:hh:mm:ss) contains either the planned or actual start time of the observation. The time_type field indicates the source of the time. C17 This field (format: yyyy.ddd:hh:mm:ss) contains either the planned or actual end time of the observation. The time_type field indicates the source of the time. C1 (P/A) When this field is P for planned, start_time and end_time are generated from SPSS planning data and the accuracy is questionable. When this field is A for actual, start_time and end_time have been updated by the OPUS pipeline using science data.
