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 com-
    ponents.

    The SPECTRAL_CLEAN method can improve deconvolution of spectrally  well  re-
    solved  faint  line wings, yielding more accurate integrated line fluxes, at
    the cost of some extra computations.  However, SPECTRAL_CLEAN  can  be  ham-
    pered  by strong velocity gradient, that require supports that differ widely
    among channels.


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