FITS

        LAS\FITS READ  file[.fits]
        LAS\FITS  WRITE  file[.fits]  /MODE  SPECTRUM|INDEX  [/BITS   nbits]
    [/CHECK]

    Either  READ  the file.fits FITS file to the CLASS internal data format.
    Please note that not all FITS files may be read by CLASS, and some head-
    er information might be incomplete when doing so.

    Or  WRITE  the  file.fits FITS file from the CLASS internal data format.
    /MODE is a mandatory argument which can take the following values:

    SPECTRUM   a simple FITS file is written from the current spectrum
               in memory is written.
    INDEX      a FITS BINTABLE is written from all the spectra in current
               index. The USER MUST make sure that all index spectra are
               consistent (same source, same line, same frequency setup,
                   ...)
    The number of bits per intensity value used when writing the  FITS  file
    may be controlled through the /NBITS optional argument. It can be: 16 or
    I*2(2 bits integer), 32 or I*4 (4 bits integer) or -32 or  R*4  (4  bits
    real).

    The  default  mode  and number of bits can also be specified through the
    commands
    SET FITS BITS nbits
    SET FITS MODE SPECTRUM|INDEX

    /CHECK will print the FITS HEADER on the terminal.
