Survey/Catalog indicators

Prefixes and designator-forms used to cite entries in various astronomical catalogs, e.g., astronomical surveys. This list is prefixes "seen in the wild", not all of which adhere to standardization efforts. To specify with a designator designed to be unique, consult SIMBAD's Dictionary of Nomenclature of Celestial Objects
