Hamanowicz ======================================================================= mpawlak@astrouw.edu.pl This directory contains the OGLE catalog of Eclipsing Binaries in the fields toward the Small Magellanic Cloud. The directory structure is as follows: README - this file ident.dat - identification of stars ecl.dat - parameters of stars phot/I/ - I-band OGLE-IV photometry of individual objects phot/V/ - V-band OGLE-IV photometry of individual objects phot.tar.gz - gzipped phot/ directory fcharts/ - finding charts of individual objects paper.pdf - PDF version of the paper Pawlak et al. (2016), describing the catalog. Format of the file ident.dat: -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 17 A17 --- Star's ID 21- 23 A3 --- Subtype of binary star (C - contact, NC - detached or semi-detached, ELL - ellipsoidal) 26- 27 I2 h Right ascension, equinox J2000.0 (hours) 29- 30 I2 m Right ascension, equinox J2000.0 (minutes) 32- 36 F5.2 s Right ascension, equinox J2000.0 (seconds) 38 A1 --- Declination, equinox J2000.0 (sign) 39- 40 I2 deg Declination, equinox J2000.0 (degrees) 42- 43 I2 arcmin Declination, equinox J2000.0 (arc minutes) 45- 48 F4.1 arcsec Declination, equinox J2000.0 (arc seconds) 51- 66 A16 --- OGLE-IV ID 68- 82 A15 --- OGLE-III ID 84- 98 A15 --- OGLE-II ID 100- A --- Other designation (from GCVS) -------------------------------------------------------------------------- Format of the files ecl.dat: -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 17 A17 --- Star's ID 21- 26 F6.3 mag Intensity mean I-band magnitude 28- 33 F6.3 mag Intensity mean V-band magnitude 35- 46 F12.7 days Period 49- 57 F9.4 days Epoche of primary eclipse 60- 64 F6.3 mag Depth of primary eclipse 66- 71 F6.3 mag Depth of secondary eclipse -------------------------------------------------------------------------- Format of the files with photometry (phot/I/OGLE-SMC-ECL-NNNN.dat, phot/V/OGLE-SMC-ECL-NNNN.dat) -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 10 F10.5 days Heliocentric Julian Day - 2450000 12- 17 F6.3 mag Magnitude 19- 23 F5.3 mag Uncertainty of magnitude -------------------------------------------------------------------------- Finding charts are gzipped Postscript images. The names of the files are in the form: ID.ps.gz. The finding charts are 60"x60" subframes of the I-band reference frames centered on the star. White cross marks the star. North is up and East to the left. Any presentation of the scientific analysis or usage of the data from the catalog of Eclipsing Binaries in the Small Magellanic Cloud should include the appropriate reference(s) to OGLE paper(s).
