The NOMAD-1 Catalog
(1117612732 rows)
The Naval Observatory Merged Astrometric Dataset (NOMAD) contains astrometric and photometric data for over 1 billion stars derived from the Hipparcos (
I/239
), Tycho-2 (
I/259
), UCAC2 (
I/289
), and USNO-B1.0 (
I/284
) catalogs for astrometry and optical photometry, supplemented by 2MASS (
II/246
) near-infrared photometry.
