SPECTRAL_CLEAN

        [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.
