### On the [rgb]1,0,0IMAGER side

The UVFITS files have first to be converted to uv tables. This can be done by a simple script

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

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

The violet`fits_to_uvt` script is based on the magenta`FITS` command of red 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 violet`fits_to_uvt` script has a number of options. Help can be obtained by typing

magenta`@` violet`fits_to_uvt` magenta`?`

Direct reading of UVFITS data is also partially supported: see Section .
