    [/LINE LineCube] [/FORCE What Value]

    Read  the  spectra cube stored in input DataCube and convert it in a set
    of spectra automatically written in the currently  opened  output  file.
    The  spectra cube can be ordered in LMV, VLM, LVM, etc... FITS files are
    automatically converted.

    By default, the command sorts the spectra to mimic the scanning path  of
    a  telescope  along the lambda direction, shifted on beta for each scan.
    Each constant beta row has a unique SCAN number. The sorting can be  ro-
    tated by 90 degree by using the /SCAN BETA option.

    Fully blanked spectra in the input cube are ignored. If the cube spatial
    axes are largely oversampled, the /STEP option allows the user to select
    1  spectrum  every  DLAMBDA (resp. DBETA) in the LAMBDA direction (resp.
    BETA). If DBETA is omitted, it defaults to DLAMBDA. The default value of
    DLAMBDA  and DBETA (if the /STEP option is not invoked) is 1, implying a
    conversion of the whole cube.

    User should take care that many parameters of the CLASS spectrum headers
    have no meaning here. They are left to their default values.

    If  /LINE provides a LineCube which matches exactly the DataCube (dimen-
    sions, coverage, source name, ...), each  spectrum  extracted  from  the
    DataCube  is  exported  with  a LINE Associated Array extracted from the
    LineCube. The LineCube should encode with 1 the parts of the cube  where
    there is signal, and 0 where there is no signal. The LINE Associated Ar-
    ray can be reused later on with the commands SET WINDOW /ASSOCIATED  and

    If  /FORCE is present, elements from the cube header can be overriden at
    import time. For now, only the scale unit can  be  customized  with  the
    keyword UNIT:
      /FORCE UNIT Value
    where  value  is a keyword for supported scale units. This is useful for
    cubes imported from outer world where the scale unit  syntax  may  vary.
    Type "LMV cubename /FORCE UNIT ?" for possible choices.
