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 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 Cepheids from the LMC should include the appropriate
reference(s) to OGLE paper(s).
