SPECTRAL_CLEAN WAVE

        [BUNDLES\]SPECTRAL_CLEAN WAVE

    Clean  a  Wavelet  Transform  along the spectral axis of the DIRTY cube, and
    transform back the Clean components to retrieve the per-channel Clean compo-
    nents. The final Clean image is produced using UV_RESTORE.

    The noise level is not the same for the wavelet components of the data cube:
    this is taken into account by the method to Clean each wavelet  image  plane
    to its proper noise level.

    Apart  for the time required by the Wavelet transform, the method has a com-
    parable speed to a standard Clean.
