Finding charts are gzipped Postscript images. The finding charts are
30"x30" subframes of the I-band reference frames centered on the star.
White cross marks the star. North is up and East to the left. Some stars
in the center of the cluster are hardly visible due to crowding.


Any presentation of the scientific analysis or usage of the data from the
OGLE collection of variable stars should include appropriate references
to OGLE papers.
