Simulation parameters

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.

CC SN lightcurves are based on the Nugent templates in sncosmo, assuming the absolute magnitude distributions from Richardson et al. (In case of the IIn's the distribution is truncated at 1 sigma on the bright side to avoid very bright lightcurves.) For the total CC SN rate 1.5 x 10^-4 yr^-1 Mpc^-3 is used and split into 80% IIP, 15% Ib/c, and 5% IIn.
SNe are simulated up to z = 0.2 with the exception of IIP's, which are only simulated up to z = 0.15 (due to high rate and low luminosity).
The survey plan is based on Peter's code that calculates which fields are observable in a given night. Afterwards the iPTF observation history of 2016 was used to throw out nights in a realistic way, including a two-week gap.
