The catalog of sources to be injected (provided through --injected-fn) should contain the following columns:
ra,dec(degree)flux_g,flux_r,flux_z: including galactic extinction (nanomaggies)sersic: Sersic index 1shape_r, half light radius (arcsecond)shape_e1,shape_e2: ellipticities 2seed: random seed, to add noise
Examples of how to produce these catalogs are given in bin/preprocess.py.
