Catalogs and the registry

Stub

Final content will cover the three ways to point acid at your data: a Python dict, a YAML file, or a directory of HATS catalogs.

Topics planned:

  • Pointing --db (or catalogs=) at a directory of HATS catalogs. Auto-discovery rules; what gets included and what gets skipped (margin caches, collections).
  • A worked YAML registry, every field commented.
  • Per-catalog overrides: ra_col, dec_col, hpix_order, neighbor_path, neighbor_margin_arcsec, npix_suffix.
  • Registering MOC footprints in the same YAML.
  • Working with non-HATS parquet directories.

Until this page lands, the README's "Catalog registry" section is the authoritative reference.
