Abstract
The comprehensive review of the FOS calibration under the POA activity aims
at a substantial improvement of science quality for the 24136 data sets in
the FOS archive. Two important aspects are (a) the trustworthyness of the
header information associated with the actual data, and (b) the confirmation
that commanding at all epochs resulted in the proper execution of planned
observations onboard at all epochs. Both questions bear relevance to the
necessity of "exception lists" and logics in the pipeline processing. In the
present report we describe the steps undertaken to verify the GIMP related
commanding and telemetry with reference to the code used in PASS and with
reference to the geomagnetic model and HST ephemeris used in the POA
pipeline code.
