MAP_CONVOLVE Resolution

          Most MAP_CONVOLVE methods do not result in a well-defined angular res-
    olution.  The only exception if for the GAUSS method applied to data with an
    existing beam, and with a minor axis argument that is larger than the exist-
    ing beamsize.. In this case GAUSS will smooth  the  data  to  the  specified
    (isotropic) angular resolution.
