This section documents warnings and errors generated by this task (if any). Note that warnings and errors can also be generated in the SAS infrastructure libraries, in which case they would not be documented here. Refer to the index of all errors and warnings available in the HTML version of the SAS documentation.

  The PIXELS table references frame numbers that were not found in the EXPOSURE table. This could be due to corrupted data or improper sorting of the tables.
corrective action: All pixels associated with the missing frames are discarded.
  A pixel has coordinates outside of the telemetered window. This could be due to a corruption or misinterpretation of the shape code.
corrective action: The pixel is discarded.
  The CCF has multiple bad pixel entries at or overlapping the same coordinates. This indicates a poorly constructed CCF.
corrective action: The duplications are discarded, but the order of precedence is not defined.
  Bad pixels listed in the CCF as uplinked or dead are present in the telemetry. This is a clear indication that the CCF is incorrect.
corrective action: The dubious CCF entry is accepted as correct.
  There may be cause for concern when a non-uplinked bad pixel listed in the CCF as hot is not also discovered by the hot pixel finding algorithm.
corrective action: The hot pixel finder is assumed to have missed these pixels.
  A CCF bad pixel listed for HTR mode data refers to less than a whole column.
corrective action: The fatuous CCF entry is extended to fill the whole column, though most likely it is completely bogus.
