DESCRIPTION

SPECSHIFT shifts all spectra in a cube according to a 2-D template (a velocity field). The velocity of the template is made the central pixel of the spectrum. If the template is blanked or out of range the spectrum is unchanged. Based on Bart Wakker's HANNING.  

PARAMETERS

in
The input data cube. vxy and xyv images are acceptable inputs. No default.
region
The region of the input cube to modify. By default the whole cube is processed.
tin
The template image, should be 2-D with same RA/DEC axes as the input cube.
refpix
The velocity pixel which will be assigned to the template velocity. Default is the middle pixel of the v-range.
options
doblank Don't wrap profile around; blank if out of range.
           By default the edge channels are assumed to be noise
           so the profile is wrapped when shifting beyond edges.
out
The output image.
