Issue DM-6893: Controlled Test of LMSimpleShape using high SNR objects
Some issues came up during DM-6300 which indicated that a more controlled set of tests would be required than the random Great3Sims tests to understand the behavior of NGMIX LMSimpleShape. LMSimpleShape appears to fail computing moments on low SNR objects. It also shows pretty wide variation in shear bias which did not show up with CModel. The needed tests with would include controlled profiles (Gauss, Dev, and Exp), controlled SNR, and controlled q, theta, and flux. This should separate out the causes of failure and shear variation which we have seen.
