Data Quality Record

Finally there will be a data quality record for each instrument exposure and one for the spacecraft data. The following data quality information will be stored stored in the summary file: These items will be stored on a per exposure basis for each instrument and on a per observation basis for the spacecraft telemetry.

  1. Identifies the record as a Data Quality Record.
  2. The syntax is ii (Section [*]).
  3. All comments will have the syntax ' / text'.
  4. The syntax is ppppppoolliieee (Section [*]).
  5. Number of telemetry packets associated with the instrument/ spacecraft that failed reception during the period.
  6. Number of event reports produced by the instrument/ spacecraft during the period.
  7. Number of errors detected by the automatic telemetry processor for the instrument/ spacecraft during the period.
  8. Number of drops in the instrument/ spacecraft telemetry during the period.
  9. Total duration of the telemetry drops in the instrument/ spacecraft telemetry during the period.
  10. Number of out of limits detected in the instrument/ spacecraft telemetry during the period.
  11. Flag (S, U or X) indicating whether the exposure was scheduled (S) or unscheduled (U) and set to 'X' when it is not applicable (for the spacecraft data quality records).
