This directory contains the sixteenth part of the OGLE-III Catalog of
Variable Stars - eclipsing binaries in the Small Magellanic Cloud.

The directory structure is as follows:

README            - this file
ecl.dat           - parameters of stars
ident.dat         - identification of stars
phot/I/           - I-band photometry of individual objects
phot/V/           - V-band photometry of individual objects
phot.tar.gz       - gzipped phot/ directory
fcharts/          - finding charts of individual objects
remarks.txt       - additional information about some objects
pap.pdf           - PDF version of the paper Pawlak et al. (2013),
                    Acta Astron. 63, 323, (arXiv:1310.3272) describing the
                    catalog.

Finding charts are gzipped Postscript images. The names of the files are in
the form: OGLE-SMC-ECL-NNNN.ps.gz. The finding charts are 60"x60" subframes
of the I-band reference frames centered on the stars. 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 SMC should include the appropriate
reference(s) to OGLE paper(s).
