18.34.23 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NAME is no longer used, and WEIGHT_MODE is obsolete.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are obsolete, superseded by MAP_CENTER.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 compatibility with older scripts.

MAP_BEAM_STEP is replaced by BEAM_STEP. An alias is provided for compatibility reasons.

MAP_TRUNCATE is replaced by MOSAIC_BEAM. An alias is provided for compatibility 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 MCOL is superseded by the /RANGE option facility.
