Compute purity and completeness for stars, galaxies for DC2 Run2.1i
wmwv opened this issue · comments
- Compare the Object (coadd) catalog with the truth catalog to calculate purity and completeness for star-galaxy identification as a function of magnitude.
- Compute a variability metric and compare its additional distinguishing power.
- May need to include some systematic stochastic intrinsic variability parameter for each of stars and galaxies (AGN?).
- Compute a seeing-weighted variability metric to identify stars vs. galaxies by * how their magnitude changes under different seeing.
