Beginning of ReadMe : I/297 NOMAD Catalog (Zacharias+ 2005) ================================================================================ Naval Observatory Merged Astrometric Dataset (NOMAD) Zacharias N., Monet D.G., Levine S.E., Urban S.E., Gaume R., Wycoff G.L. <San Diego AAS Meeting, January (2005)> =2004AAS...205.4815Z ================================================================================ ADC_Keywords: Positional data ; Proper motions ; Surveys ; Photometry, photographic ; Photometry, infrared Description: 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. For each unique star the "best" astrometric and photometric data are chosen from the source catalogs and merged into a single dataset. A sequence of priorities is followed and NOMAD contains flags to identify the source catalogs and gives cross-reference identifications. This first release of NOMAD is not a compiled catalog; that is, if a star is identified in more than 1 of the above mentioned catalogs, only 1 catalog entry is chosen. Thus the local and global systematic errors of the various source catalogs will be present in this version of NOMAD. All source catalogs astrometric data are on the International Celestial Reference System within the limitations of the source catalogs.
