E.1 Off-Line Products

Data obtained using AOTs

Most of the scientific observations and many calibration observations have been performed using pre-defined Astronomical Observation Templates (AOTs).

Data Obtained Using Non-Standard Commanding

Many data, especially those obtained during the Performance Verification Phase, from activation sequences and from calibration observations, have been obtained using non-standard commanding. Data obtained using the Calibration Uplink System are an example. Since all these data are of scientific interest, usually the same range of products as defined for AOT-derived data are available. An exception is PHT, for which only ERD is available for these observations (including the two polarisation modes PHT50 & PHT51).

Parallel and Serendipity Data

CAM, PHT and LWS have data which were obtained when the instrument itself was not prime, such as during slews or when other instruments were in staring or raster mode. A suitable range of raw and processed data, as far as possible mirroring of those for AOT-derived data, have been defined and archived. Again, for PHT serendipity mode only ERD data are available.

An overview of the files per product level for each instrument can be found in Tables E.1,  E.2 and  E.3.

E.1.1 Quality flags

• General:
  • Good: No technical problems.
  • Unknown: The quality assessment was not made for non-standard observations. `Unknown' appears for all AOT99 observations (except CAM99), parallel & serendipity and engineering modes.
  • Never Executed

• Processing problems:
  (problems encountered during the different pipeline processing steps; a number of products are missing)
  • Raw and basic science data OK: The first two levels of data products have been derived. Auto-processed data missing.
  • Raw data OK: Only the first level of data products could be derived. Basic science data and auto-processed data missing.
  • No science data available: No data products could be derived.
• Real-Time problems:
  (problems during operations of satellite, instruments or with the communication link)
  • TM drop: The data are heavily affected by an interruption of the telemetry.
  • Poor pointing: The actual pointing was significantly off the target, or the target was not acquired at all.
  • Instrument malfunction: The data are heavily affected by a problem in one of the instrument components.

Further information on all events during a specific ISO revolution can be found in the `Real-Time Revolution Reports' (RRPs), in the Observations Details panel.
