MODIFY DOPPLER

            CLIC\MODIFY DOPPLER

        Computes the Doppler velocity correction, in case it was not  taken into
        account  at  the  time of observing.  The LO2 frequency in the header is
        assumed to be the frequency actually used.  A warning   is   issued   if
        the  LO1  frequency in the header is not coherent with the LO2 frequency
        (which means the phase tracking might be in error, since  it  uses  that
        LO1 frequency).

        The  frequencies  and line names introduced by SET FREQUENCY are used to
        define the velocity scales for each subband/sideband.
