lsstdesc/photozdc1

How lsstdesc/photozdc1 works

This is a Python toolkit for generating galaxy photometry/catalogs from mock-galaxy properties and studying photo-z performance under configurable systematic effects. The intended workflow is to read a mock catalog, assign or generate SEDs, model perturbations, compute observed magnitudes, and assess resulting photo-z statistics. The README describes some stages as planned rather than implemented; links for those capabilities are documented or left unverified. Source excerpts and the index establish only a subset of runtime wiring.
