Description
The GBT Antenna FITS file contains information on the telescope pointings.
The pointing information is normally sampled 10 times a second. The filler
computes a mean pointing direction over each integration and stores that value
in the DIRECTION column of the POINTING subtable. When the fillrawpointing
flag is F(alse) (the default value) the raw, unaveraged, pointings are not saved
in the MeasurementSet in order to save space. This behavior can be changed by
setting this flag to T. When this flag is true, the raw pointings can be
found in the NRAO_GBT_POINTING subtable. This decision must be made before the
MeasurementSet is filled.
