            [BUNDLES\]SPECTRAL_CLEAN MODE [Control ]

          Perform a Clean with different spectral scales.

           MODE can be
             FFT       Clean the Fourier Transform of the spectra
             WAVE      Clean a Wavelet Transform of the spectra
             DUAL Ns   Clean at two different spectral resolutions
             MULTI Ns  Clean at two (or more) spectral resolutions.
        Instead  of  Cleaning  separately  individual  channels,  SPECTRAL_CLEAN
        cleans  either  Spectral  Transform of the data cube (along the velocity
        axis), and performs the inverse transformation to restore  the  channel-
        based Clean components.

        The  SPECTRAL_CLEAN  method can improve deconvolution of spectrally well
        resolved faint line wings, yielding more accurate integrated line  flux-
        es, at the cost of some extra computations.  However, SPECTRAL_CLEAN can
        be hampered by strong velocity gradient, that require supports that dif-
        fer widely among channels.

        Standard  CLEAN  control parameters apply. However the METHOD must allow
        retrieving Clean Componentes: MRC is thus excluded.  SPECTRAL_CLEAN  can
        also work on Mosaics.
