=============================================================================== Lick Northern Proper Motion Program: NPM2 Cross-Identifications and Appendices A.R. Klemola, R.B. Hanson, B.F.

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". We thank the National Science Foundation for its long-term support of the NPM program. The NPM2 phase was supported by NSF grants AST-9530632 and AST-0088105.
