Five-Point steps the telescope through the sequence off on +maj -maj
+min -min on off, where maj is the R.A. or Longitude Offset,
and min is the Dec., latitude, or elevation Offset. This
procedures primary purpose is to determine pointing offsets. If you
are observing in Azimuth/Elevation coordinates, the blank sky off
position will be 5 times the Az. Offset distance from the central
position. Otherwise, an additional Az. Offset parameter is specified.
Point Integration is the integration time on each position. Unless
Separate Scans = no, each integration will be recorded as a separate
scan.
The available keywords for the fivepoint procedure are
shown in Table 3.7.
