Summary of HIPASS declination scans
The HIPASS survey is conducted using declination scans of length 8.6 deg,
with the receiver rotated at position angle 15 deg. The telescope scan
rate is 1 deg/min, and the correlator is read out every 5 sec. The
following table contains: the central dec of each scan; the step in
RA (degrees of polar rotation) between successive primary scans; the
number of scans to cover the full RA range 0-24 hr; the number of interleaves
(each interleave scan being displaced by 7 arcmin in RA); the total number
of scans; and the number of virtual pointing centres (for final cube
formation).
