ident.dat         - identification of stars

t2cep.dat         - observational parameters of type II Cepheids

phot/I/           - I-band photometry of individual objects
phot/V/           - V-band photometry of individual objects
phot.tar.gz       - gzipped phot/ directory

fcharts/          - finding charts of individual objects
                       
remarks.txt       - remarks on selected objects

pap.ps.gz         - postscript version of the paper Soszynski et al. (2011),
                    Acta Astron. 61, 285, (arXiv:1112.1406) describing the
                    catalog.

Finding charts are gzipped PostScript images. The names of the files are in
the form: OGLE-BLG-T2CEP-NNN.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 type II Cepheids in the Galactic bulge should include the
appropriate reference(s) to OGLE paper(s).
