18.12.8 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 brightness temperature in K.

Accordingly, when the GAUSS method results in a well-defined angular resolution, 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 conserve flux.

For all other units, it is up to the user to properly interpret the smoothing effect.
