Radial specific intensity profiles for four SN Ia models (W7, N100, the sub-Ch, and the merger model in the four labeled columns) for the six LSST filters at rest-frame day 14.9 (top row) and day 33.8 (bottom row) after explosion, where R_Ein = 2.9 × 10¹⁶ cm for the median source and lens redshifts (z_s, z_d = 0.77, 0.32) based on OM10. Different SN Ia models yield different specific intensity profiles, leading to different durations of the achromatic phase. The wiggles for low p values at day 14.9 are most likely due to Monte Carlos noise and we do not expect them to be physical. For our microlensing calculations, differences at higher p values are more relevant, since events where micro caustics are crossed become more likely with larger radius.
