Surprising transient distributions out to z=3 #884

This may be due to our setup, but the new SCOTCH sims are leading to a suprising distribution where the rate of events tends to peak around z=1 and drop past that. The log files are on NERSC in /global/cfs/cdirs/lsst/groups/TD/SN/SNANA/SURVEYS/LSST/ROOT/PLASTICC_DEV/survey_config/SIMLOGS_AGML_GP_SCOTCH10k_KN_0414 and /global/cfs/cdirs/lsst/groups/TD/SN/SNANA/SURVEYS/LSST/ROOT/PLASTICC_DEV/survey_config/SIMLOGS_MLAG_GP_SCOTCH10k_0412 (KN, then all other classes) and from what we can tell, Genperfect is working fine, the KN rates are consistent at every redshift, and all events are being observed. We use the new SIMSED binaries in /global/cfs/cdirs/lsst/groups/TD/SN/SNANA/SURVEYS/LSST/ROOT/PLASTICC/model_libs/SIMSED_BINARIES/config_SCOTCH/ and put GENRANGE_REDSHIFT: 0.023 2.95 in GENOPT_GLOBAL to override every other instance. We have GENPERFECT set to 10 and NGENTOT_LC set to 250 per run (simulating 10,000 events total)

The distributions were actually as expected when you account for the evolution of comoving volume with redshift and include time dilation! Not an issue after all.
