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.

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).
