Modifications for DDF instance catalog generation #86

Open jchiang87 opened 4 years ago

jchiang87 commented 4 years ago

There are a couple of changes we should consider for the DDF sims:

  1. Add an option to turn off instance catalog generation for stars and galaxies. Since we're starting from the checkpoint files from the static sims, we don't need these object classes to be generated. This will save a lot of compute time.
  2. In the AGN flux calculations, the light curves are computed for all six bands, even though only the band corresponding to the visit being considered is needed. We should be able to skip the other 5 bands that aren't needed and recover a factor of 6 in speed up for this part of the calculations.
