Predicted AB apparent magnitudes in the Gemini u, g, i, and K_s bands for an observer at a polar angle of 30 degrees and a distance of 40 Mpc. Comparison between the simulations using in situ NN (solid lines) and analytical nuclear power fits (dashed lines). All models adopt simple (no composition-dependent) thermalization and opacity models. The left and right panels show results for the BLh and DD2 ejecta profiles, respectively.
