Description
Reduces a pointing observation made with the GBT. Baselines are fit from the
two edges of the scan only. The parameter basepct specifies the percentage of
the total scan used from each edge. For example, a basepct of 10 means that
a tenth of the scan at each of the two edges is used in calculating the
baseline. If xaxis=0, the function will
attempt to determine whether RA or Dec is appropriate for the given scan.
