Produce new truth catalogs #41

Open cwwalter opened 7 years ago

cwwalter commented 7 years ago

I believe the current star and galaxy truth catalogs were produced by @jchiang87 by processing the instance catalogs.

Perhaps here? https://github.com/LSSTDESC/pserv/tree/u/jchiang/add_imsim_truth/sql

One of consequences of this is that the disk and bulge components of galaxies are entered separately int the truth tables (as this is how they are simulated). We should probably generate the truth tables directly from the CatSim database. We should also consider adding information non in the instance catalogs such as the stellar population id.

Anything else we should include?

I should have included @danielsf in the above issue.

Chris already has scripts to do this from dataframes created by querying the pserv/mysql database tables with the truth info, so we'll take that approach for now. For the future (i.e., DC2, et al), we will look into the CatSim-based approach.
