FITS READ

            LAS\FITS READ File[.fits]

        Read the File.fits FITS file to the CLASS Data Format. If the FITS  file
        has been written (see HELP FITS WRITE) using:
        -  the  SPECTRUM  mode,  the (unique) spectrum is loaded in the R buffer
          (memory only). If needed, you have to open an output file and WRITE it
          in order to save it on disk.
        -  the  INDEX  mode,  the (several) spectra are converted and implicitly
          written to the current output file (it must have been opened  before).
          The  previous contents of the Class file is preserved (spectra are ap-
          pended).

        This command can read 2 flavors of FITS files:
        - the CLASS-FITS format (i.e. the one written by FITS WRITE or  by  some
          3rd  party  softwares). See the CLASS programmer documentation for de-
          tails.
        - the Herschel-HIFI FITS format. See the dedicated memo for details.

        FITS cubes can be converted to the Gildas (not CLASS) Data Format by the
        command  VECTOR\FITS,  and then imported as a Class index by the command
        ANALYSE\LMV. See HELP V\FITS and HELP LMV for details.
