On the IMAGER side

The UVFITS files have first to be converted to uv tables. The easiest way is to use the PIPELINEORGANIZE command. Alternatively, this can be done by a simple script

  sic find *.uvfits
  for string /in dir%file
    @ fits_to_uvt 'string'
  next

Each Source-Frequency.uvfits file will be converted to a Source-Frequency.uvt uv table (the original .uvfits file is kept too).

The fits_to_uvt script is based on the FITS command of SIC, but augmented with a number of tests to recognize the proper layout of the UVFITS file, as this layout depends on which CASA version was used, and whether it is a single source or multi source file.

The fits_to_uvt script has a number of options. Help can be obtained by typing

@ fits_to_uvt ?

Direct reading of UVFITS data is also supported, but with limited capabilities: see Section 5.5.
