mom2cube - Use cube moments along Z to reconstruct a cube
mom2cube
[parameter=value]
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.
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)
