COBE DIRBE Zodiacal Light Prediction Software

This is software written in IDL for calculating the zodiacal light predicted from the DIRBE team interplanetary dust model (Kelsall et al. 1998, ApJ, 508, 44). This model was obtained by fitting the time variation of DIRBE all-sky observations over 10 months with a parameterized model of the dust cloud. Thus it is constrained over solar elongation angles ranging from 64 to 124 degrees.
