SET GIBBS

        CLIC\SET GIBBS number

    Give the number of channels to be masked on each  side  of  the  central
    frequency,  for the correlator subbands which are obtained by juxtaposi-
    tion of both sidebands of a common (third) local oscillator.  Due to the
    Gibbs  effect, a few channels are corrupted by a contribution of the im-
    age sideband of the first local oscillator, which may contain signal  if
    the source has continuum emission.  This is the case for the 160 and 320
    MHz bands at the Plateau de Bure correlator.

    The GIBBS number is used by further PLOT and TABLE commands. The default
    is 0, which is relevant for line sources with no continuum emission.
