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).
