GBT Software Project Note 11.2
The FITS format structure is presented for the GBT Calibration
(Receiver) scan data files. The scan data FITS files are permanently
archived after each observation, and will usually be input to the
aips++ filler, which has the task of combining all scan data FITS
files into an aips++ Measurement Set. This data may then either be
processed further in aips++, or written out in an aips++ supported
FITS format (one of which is single dish FITS).
The Calibration FITS file produced for each receiver contains binary
tables of the smoothed, interpolated calibration temperatures
for each receptor. In addition, the primary header contains default
values of various efficiencies and atmospheric opacity, which may
be used for subsequent data processing.

- Penultimate definition of FITSVER 1.1; released
for general comment (Richard Prestage).
- 16th November 2001
- Final version agreed for implementation of
FITSVER 1.1. Added history. Subsequent changes to the content of this
document should increment the document version number (Richard Prestage).
- 31st July 2007
