The authors present the results of Monte Carlo calculations of the γ-ray spectra for a grid of models that spans the parameter space associated with the radioactive decay model of SNIa. They give tables of equivalent widths and background flux levels for three of the strongest lines in the γ-ray spectrum, at 0.511, 0.847, and 1.238 MeV. Also given is a table of net γ-ray and X-ray luminosities.
