Task: deproject Purpose: deproject an image Categories: map analysis 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 Key: in Input data cube. No default. Key: out Output data cube. No default. Key: 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. Key: pa major axis position angle (degrees) Key: inc inclination to be deprojected (degrees) Key: osize Optional forced output size in X and Y. By default size is choosen from ... Key: ocenter Optional output position for galaxy center. By default the output center is the same as the input center Key: iflux flag to attempt some manner of flux conversion [Integer: 0 = Don't bother (default) 1 = Sure why not ] Key: invert flag to invert the deprojection transformation (i.e. project image) [Integer: 0 >= Deproject image (default) -1 = inverse transfomation (project image)]
