*in*- The input image. No default.
*region*- The region of the input image to be used. See documentation for region on how to specify this. Only the bounding box is supported.
*out*- The output image. No default.
*mom*-
-3 Velocity at peak, using a 3 point polynomial fit around the peak
-2 Peak temperature (units are same as individual channels)
-1 Average intensity. (units are same as individual channels)
0 Integrated intensity. (e.g. units I x km/s) 1 1st moment = sum(I*v)/sum(I) 2 dispersion = sqrt(sum(I*(v-M1)**2)/sum(I)) The v(i) are the axis values (e.g. velocities). M1 is the first moment. The moment is calculated independently for each pixel within the specified clip range. Default = 0. Note that mom=2 produces a map of sigma ('gaussian' dispersions), with FWHM = 2*sqrt(2*ln(2)) = 2.355 * sigma if the profile was a true gaussian.

*axis*
The axis for which the moment is calculated. Default = 3.
*clip*- Two values. Exclude pixels with values in the range clip(1) to clip(2). If only one value is given, then exclude -abs(clip) to abs(clip).
*rngmsk*- Mask pixels as bad when the 1st moment gives a 1st moment out of range of that of the axis. This option can only be activated for mom=1. Default: false
*raw*-
By default, moment is user oriented, i.e. mom=1 computes the velocity.
By setting raw=true, you will get the raw sum(I*v**mom) and will have to use
MATHS to compute back the various maps.
Currently only supported for axis=3.
If the velocity scale is very large and/or mom is large, a rescale
using PUTHD on crval3/cdelt3 may be needed.
Default: false
