This is the task to convert single-dish scantable data format (ATNF Spectral Analysis Package, ASAP) into a CASA visibility data format (MeasurementSet, MS) to enable processing of scantable-format datasets (e.g. Parkes, Mopra Telescopes at ATNF).

Prior to CASA 4.5, most of the ALMA data reduction process was done in Scantable format. Later CASA versions shifted towards eliminating the dependence on Scantable format. From CASA 5.0, no processing/reduction is done in Scantable format, and data with Scantable format must be transformed into MS format before reduction.
