            CLIC\FITS name [/PLOT] [/BASELINE b] [/ANTENNA a] [/OVERWRITE]

        Create for each selected line subband a FITS file containing  the  spec-
        tral  data.  The  fits file names are e.g. name-l01.fits, name-l02.fits,
        name-l03.fits (one fits file is created for each subband),  if  one  has
        specified SET SUBBAND L01 L02 L03.

        For  autocorrelation data, the data from all antennas are averaged.  For
        correlation data, the complex data from all baselines are  averaged  and
        the real part of the resulting visibility is used.

        Option /ANTENNA exports a single logical antenna for autocorrelation da-
        ta instead of averaging all antennas together.  Option /BASELINE exports
        a  single logical baseline for correlation data instead of averaging all
        baselines together. The baseline label uses the same logical notation as
        in  SET  BASELINE.   Option  /PLOT displays the selected spectrum before
        writing the FITS file.

        Only one selector can be specified. Use /ANTENNA only  for  autocorrela-
        tion  data  and  /BASELINE only for correlation data.  Option /OVERWRITE
        allows replacing an existing output FITS file.

        This command allows to easily write out spectra from point-like  sources
        to  be  further analyzed in CLASS. Reading the data in CLASS and writing
        them in a CLASS-format file can be done with a procedure like:

            FILE OUT myfile NEW
            FITS READ name-l01.fits
            WRITE next_obs
            FITS READ name-l02.fits
            WRITE next_obs
            etc..
