BEAM_STEP

      BEAM_STEP   Integer

    Number of channels per synthesized beam plane.

    Default  is 0, meaning only 1 beam plane for all channels.  N (>0) indi-
    cates N consecutive channels will share the same dirty beam.

    A value of -1 can be used to compute the number  of  channels  per  beam
    plane  that  ensures that the angular scale does not deviate more than a
    fraction of the map cell at the map edge. This fraction is controlled by
    variable MAP_PRECIS (default 0.1)
