NAME

rotcurmask - Create a mask cube based on a rotation curve model  

PERSON RESPONSIBLE

pjt  

CATEGORIES

image analysis  

DESCRIPTION

ROTCURMASK creates an output mask cube from an input data cube based on a adaptive window around a velocities from a model velocity field. The output mask cube can then be used in MOMENT to create a more realistic velocity field.

Warning: ROTCURMASK allocates two full MAXDIM3*MAXDIM3 maps for faster computations. (defaulted to 2048**2 maps)  

PARAMETERS

in
The input data cube. The fist two axes should be spatial, the third axis should have units km/s (or something equivalent). No default.
out
The output mask cube data set. No default.
rotmod
Input rotation model velocity field. Currently this map should have the same 2D shape as the first two (spatial) dimension of the input cube. This map can be made from MIRIAD's velmodel or NEMO's ccdvel program. Units should be km/s.
mom2
Optional map of velocity dispersion (e.g. created from MOMENT MOM=2) to control the window size. If none is given, the MINSIGMA parameter (see below) will be used as a global number. Optionally an mom2 map can also be created using IMGEN. Units of this map should be km/s.
minsigma
Minimum sigma, in case mom2 has lesser (or no) value. Should be a number in units of km/s. Default: 5.
window
The multiplicative factor by which sigma is multiplied to create a window +/- max(MINSIGMA,MOM2) * WINDOW around the model velocity. Data outside this windows are masked false. Default: 3.
