PERSON RESPONSIBLE

CATEGORIES

map analysis  

DESCRIPTION

Given the center, major axis, and inclination of a galaxy, create a deprojected image. Two optional parameters are provided to allow for the output image's size and the galaxy's central coordinate to be fixed. Intensities are multiplied by cos(inc) to correct the surface brightness, assuming we have a plane parallel optically thin medium. See iflag= to control this behavior.

Caveat: image needs to have square pixels  

PARAMETERS

in
Input data cube. No default.
out
Output data cube. No default.
center
Center of the polar coordinate system, in pixels where (1,1) is the lower left point in a map. By default the mapcenter will be taken. By default the output map will preserve this as the reference pixel, but see also ocenter= below.
pa
major axis position angle (degrees)
inc
inclination to be deprojected (degrees)
osize
Optional forced output size in X and Y. By default size is choosen from ...
ocenter
Optional output position for galaxy center. By default the output center is the same as the input center
iflux
flag to attempt some manner of flux conversion
              [Integer: 0 = Don't bother (default)
                        1 = Sure why not ]
invert
flag to invert the deprojection transformation
              (i.e. project image)
              [Integer: 0 >= Deproject image (default)
                       -1  = inverse transfomation (project image)]
