Grating Angle Calculator
This is an IRAF script grating calculator written by Rick Burruss.
It solves for the grating angle needed to put your desired
wavelength onto the center of the CCD. This angle is a function of
spectral order, choice of red or blue camera geometry, and grating
lines/millimeter. All of the options are laid out in the calculator.
It is more accurate for the blue side camera given the chip size vs vignetting
and obscuration. Please see the DBSP Overview
for more information.
