This loads all of the data from filename into the scantable object scans and averages all the data within a scan (i.e. the resulting scantable will have one row per scan). The recognised input file formats are RPFITS, SDFITS (singledish fits), ASAP's scantable format and aips++ MeasurementSet2 format.
Example usage:
ASAP> scan = scantable('2004-11-23_1841-P484.rpf')
# Don't scan average the data
ASAP> scan = scantable('2004-11-23_1841-P484.rpf', average=False)
