The FITS format structure is presented for the GBT GO (Observer's User
Interface) 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 contents of the GO FITS file are intended to be indicative of
the observer's intent when performing an observation comprised of
a sequence of scans. They are not intended to provide detailed data
processing information; this should be obtained from the other FITS
files associated with each scan.
