Basic Information on specshift
Task: specshift
Purpose: shift velocity profiles
Categories: analysis
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.
Key: in
The input data cube. No default.
Key: tin
The template image, should be 2-D with same RA/DEC axes as the
input cube.
Key: out
The output image. No default.
Key: region
The region of the input cube to modify. Default is the whole
cube.
Key: refpix
The velocity pixel which will be assigned to the template
velocity. Default is the middle pixel of the v-range.
Key: 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.
