Abstract:

The parameters of the HI Parkes All-Sky Surveys (HIPASS), as proposed by the Multibeam Survey Working Group, are described, as are the advantages and disadvantages of various multibeam observing techniques, including telescope scanning. The best techniques, in terms of minimizing the variance in image sensitivity, are calculated. Some of the observing techniques may be applicable to other multibeam surveys.
