Old_Names:

        NAME is no longer used, and WEIGHT_MODE is obsolete.
        MAP_RA          [  hours]  RA of map center
        MAP_DEC         [    deg]  Dec of map center
        MAP_ANGLE       [    deg]  Map position angle
        MAP_SHIFT       [Yes/No ]  Shift phase center
        are obsolete, superseded by MAP_CENTER. They are provided only for  com-
        patibility with older scripts.

        MAP_BEAM_STEP    is replaced by BEAM_STEP. An alias is provided for com-
        patibility reasons.

        WCOL (the Weight channel) and MCOL[2] (the channel range)  are  obsolete
        also. WCOL has no meaning when more than 1 beam must be produced for all
        channels, and should be set to 0.  MCOL is superseded by the /RANGE  op-
        tion facility.

         NAME        [       ]  Label of the dirty image and beam plots
         UV_TAPER    [m,m,deg]  UV-apodization by convolution with a Gaussian
         WEIGHT_MODE [       ]  Weighting mode (NA|UN)
         UV_CELL     [m, ??  ]  UV cell size and threshold for Robust weighting
         MAP_FIELD   [ arcsec]  Map field of view
         MAP_CELL    [ arcsec]  Map cell size
         MAP_SIZE    [ pixels]  Map size in pixels (if MAP_FIELD is zero)
         MCOL        [       ]  First and Last channel to map
         WCOL        [       ]  Channel from which the weights are taken
         CONVOLUTION [       ]  Convolution function (5)
         UV_SHIFT    [       ]  Change the map phase center or map orientation?
         MAP_RA      [       ]  RA of map phase center
         MAP_DEC     [       ]  Dec of map phase center
