Basic Information on mossen
Task: mossen
Purpose: Determine the rms and gain in a mosaiced image.
Categories: map combination
MOSSEN determines the rms and gain of a mosaiced image. Both
of these parameters are a function of position (and also mildly
frequency dependent).
Key: in
The input map of interest. No default.
Key: region
The standard region of interest parameter, giving the region
where the sensitivity function is to be determined. The default
is the entire input image.
Key: sen
The output image giving the rms as a function of position.
The default is that this image is not created.
Key: gain
The output image giving the gain to a unit point source as a
function of position. To avoid noise amplification at the
edge of mosaiced regions, Miriad does not normally totally
correct for the primary beam beyond a certain point. The default
is that no gain image is formed.
