Catalog Setup Skill

Setting up astronomical catalog databases involves building, updating, and verifying source catalogs like NVSS, FIRST, and RACS to ensure data integrity and availability for subsequent radio astronomy processing stages.

You need to prepare declination-specific catalog files when a new observation run begins at a specific declination strip. This ensures the correct NVSS, FIRST, and RACS catalog databases are present and correctly formatted to prevent processing errors.

To build missing NVSS and FIRST catalogs for a specific declination, use automated catalog management tools to construct the databases from source data. This validates their integrity and aligns them with the observation's declination strip.

Yes, you can validate the integrity of existing RACS catalog databases. Validation checks ensure the catalog files are present, correctly formatted, and aligned with the observation's declination to prevent errors in subsequent processing stages.

The limitations of automated catalog setup include strict dependency on the availability of source data for building missing catalogs. It specifically handles declination-specific requirements for databases like NVSS, FIRST, and RACS, and cannot process other formats or catalogs.
