MAP_CONVOLVE Units
MAP_CONVOLVE applies a spatial smoothing of the data. It thus usually
makes sense only for brightness-like quantities, such as Jy/pixel or bright-
ness temperature in K.
Accordingly, when the GAUSS method results in a well-defined angular reso-
lution, the brightness unit Jy/beam is rescaled to the appropriate beam
size. In all other cases, the Jy/beam unit is converted to Jy/pixel to con-
serve flux.
For all other units, it is up to the user to properly interpret the
smoothing effect.
