I/293               NPM2 Cross-Identifications                  (Klemola+ 2004)

Lick Northern Proper Motion Program: NPM2 Cross-Identifications and Appendices Klemola A.R., Hanson R.B., Jones B.F., Monet D.G. <Astron. J. 128, 1430 (2004)> =2004AJ....128.1430H
ADC_Keywords: Cross identifications ; Proper motions Description: The Lick NPM2 Catalog provides absolute proper motions, positions, and photographic photometry, measured in the Lick Northern Proper Motion (NPM) program, for 232,062 stars in the magnitude range 8<B<18, covering the sky within the Milky Way north of -23deg declination. The NPM2 Cross-Identifications file provides 46,887 cross-identifications between the NPM2 Catalog numbers and star names, stellar type classifications, and publication references. These additional data, extracted from Klemola's Lick Input Catalog of Special Stars (ICSS), facilitate many practical uses of the NPM2 Catalog. Five Appendices to the NPM2 Catalog provide references, footnotes, and other useful information. This "ReadMe" file explains the file formats. Detailed documentation is given in the file "npm2cros.txt". File Summary:
