Finding charts are gzipped Postscript images. The names of the files are in
the form: OGLE-SMC-T2CEP-NN.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 type II Cepheids in the SMC should include the appropriate
reference(s) to OGLE paper(s).
