[SPRINT] Background subtraction test to shear image simulations

[EiffL]

Background subtraction test to shear image simulations

Testing the impact of background subtraction on shear recovery with the descwl-shear-sims package.

Contacts: @esheldon @EiffL Day/Time: Main communication channel: #desc-wl-shear GitHub repo: https://github.com/LSSTDESC/descwl-shear-sims

Goals and deliverable

• [ ] Adding a simple background model to the simulations
• [ ] Turn on the background subtraction
• [ ] Test the impact on (high SNR)

Resources and skills needed

Skills with python, enthusiasm needed about shear testing.

Detailed description

TBD

[esheldon]

There are two parts of this

1. add background to the sims
2. turn on background determination

The first one is in the sim package, the second occurs elsewhere. I will volunteer to work on making the stack do the bg subtraction because it isn't clear yet how/where that should happen exactly.
