vis_input_fits

Name of a FITS File containing a visibility bag for a single or multiple times and energies.

Using a visibility file as input saves time because we don't need to read the raw telemetry files again.

If the file is not in the current directory, include the file path in this file name.

When VIS_INPUT_FITS is set to a file, all of the control parameters that visibilities depend on are set as they were when the file was made. You are not allowed to change most of the control parameter. Info parameters are also filled in from the file.

To resume using the raw files as input, set VIS_INPUT_FITS to a null string.
