The most current simulation is for the SEDm white papers. It assumes 6 months of MSIP gR survey but I have also simulated a fast g-band survey starting in mid-February.
Two simulations of SN Ia lightcurves were run: one based on 1000 SED realizations from P.-F. Leget's SUGAR template and another based on the Hsiao template. The assumed rate is 3 x 10^-5 yr^-1 Mpc^-3.
