Beginning of ReadMe : I/320 SPM 4.0 Catalog (Girard+, 2011) ================================================================================ Yale/San Juan Southern Proper Motion Catalog 4 (SPM4) Girard T.M., van Altena W.F., Zacharias N., Vieira K., Casetti-Dinescu D.I., Castillo D., Herrera D., Lee Y.S., Beers T.C., Monet D.G., Lopez C.E. <Astron. J. 142, 15 (2011)> =2011AJ....142...15G =2011yCat.1320....0P ================================================================================ ADC_Keywords: Positional data ; Proper motions ; Photometry, photographic ; Photometry, CCD Keywords: Astrometry - Catalogs Description: The SPM4 Catalog contains absolute proper motions, celestial coordinates, and B,V photometry for 103,319,647 stars and galaxies between the south celestial pole and -20 degrees declination. The catalog is roughly complete to V=17.5. It is based on photographic and CCD observations taken with the Yale Southern Observatory's double-astrograph at Cesco Observatory in El Leoncito, Argentina. The first-epoch survey, taken from 1965 to 1979, was entirely photographic. The second-epoch survey is approximately 1/3 photographic (taken from 1988 to 1998) and 2/3 CCD-based (taken from 2004 through 2008). Full details about the creation of the SPM4.0 catalog can be found in the paper, and also in the document "spm4_doc.txt" file which describes the original files, accessible from http://www.astro.yale.edu/astrom/spm4cat/
