Finding charts are gzipped Postscript images. The names of the files are
in the form: OGLE-GD-ECL-NNNNN.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 binary stars in the OGLE-III Galactic disk area
should include the appropriate reference(s) to OGLE paper(s).
