| I/297/out | NOMAD Catalog (Zacharias+ 2005) The NOMAD-1 Catalog (1117612732 rows) | -c=274.2129069 -18.2492872, eq=J2000, rs=2 |
Note:
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.
An efficient remote query program findnomad1 is
available in the cdsclient
package, for Unix/Linux platforms
