Ulaczyk ======================================================================== rpoleski@astrouw.edu.pl This directory contains the OGLE-III catalog of proper motions for stars observed towards the Magellanic Clouds. The directory structure is as follows: README - this file catalog/ - subdirectory with compressed catalog files for each subfield separately (1256) whole_catalog.gz - compressed file containing catalog data for all the subfields variables.dat - proper motions of variable stars CPM.dat - list of common proper motion binaries remarks.txt - remarks on selected objects Format of the files in catalog/ subdirectory and whole_catalog.gz file: -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 15 A15 --- Star's ID: OGLE-III field and database number 17- 18 I2 h Right ascension, equinox J2000.0 (hours) 20- 21 I2 m Right ascension, equinox J2000.0 (minutes) 23- 27 F5.2 s Right ascension, equinox J2000.0 (seconds) 29 A1 --- Declination, equinox J2000.0 (sign) 30- 31 I2 deg Declination, equinox J2000.0 (degrees) 33- 34 I2 arcmin Declination, equinox J2000.0 (arc minutes) 36- 39 F4.1 arcsec Declination, equinox J2000.0 (arc seconds) 41- 46 F6.3 mag I-band brightness 48- 53 F6.3 mag V-I color 55- 61 F7.2 mas/yr Proper motion in R.A.

Similarly V-I color of "9.999" indicates V-band brightness is unknown. Data for stars with proper motions higher than 100 mas/yr were copied from Poleski et al. (2011), Acta Astron. 61, 199 (see ../hpm_mcs/ directory).
