OGLE-I Contact Binary Stars Catalog This directory contains: README - this file EW.all - table with catalog data for all contact binaries found in OGLE-I data (including those from first edition of the catalog of OGLE-I variable stars). See below for details EWa/ - subdirectory with catalogs, photometry and finding charts of EWa type binaries EWs/ - subdirectory with catalogs, photometry and finding charts of EWs type binaries P/ - subdirectory with catalog, photometry and finding charts of stars with nearly sinusoidal light curves classified as pulsating variables (for comparison) paper.ps.gz - gzipped Postscript version of the paper: "Contact Binaries in OGLE-I Database" by M. Szymanski, M. Kubiak & A. Udalski (Acta Astron. 51, 259 (2001)) Catalog data table contains following data. Stars are sorted by period. Column Description 1 OGLE-I field name 2 Star no. in the OGLE-I database 3 R.A. (J2000) 4 Dec. (J2000) 5 calibrated I mag 6 calibrated V-I color (9.99 if no data in V available for a star; I magnitude for these stars was calibrated with typical value of V-I=1.0) 7 period in days 8 type classification REMARK: Two stars survived all checks and entered the catalog twice, with two different period values: BW11 72188 (EWa) BW7 66654 (EWs)
