Name

mom2cube - Use cube moments along Z to reconstruct a cube

Synopsis

mom2cube [parameter=value]

Description

Using the first two or three moment maps, a data cube is recontructed. The third axis needs to be described, or inherited from a supplied cube.

Parameters

The following parameters are recognized in any order if the keyword is also given:
mom0=
Input moment-0 image. Units can be sum or sum*dz. See norm= below, and also ccdmom(1NEMO) with the integrate=t option. No default.
mom1=
Input moment-1 image. No default.
mom2=
Input moment-2 image. Optional. If not given, a constant sigma (see below) is used.
out=
Reconstructed output cube.
sigma=
Constant value for mom2 (sigma) if that image is not supplied.
cube=
Optional cube to describe 3rd axis, see also clone=. []
z=
Zmin,Zmax,dZ (or use cube) [-1.0,1.0,0.1]
norm=t|f
Normalization of the cube? This will make sure that the values mom0 correspond to the integral in the cube (I.dv) not just the sum of the values. [true]
clone=t|f
Should the cube be cloned (including WCS). This also saves memory, but can only be done if they spatially agree in X and Y. [false]
chan0=
Select a channel to be zero’d out. This can be useful if you need the cube for a simulation where there is a channel with no signal. Default: -1 (no channel zeroed)
