This directory contains the fourteenth part of the OGLE-III Catalog of
Variable Stars - Type II Cepheids in the Galactic bulge.
The directory structure is as follows:
README - this file
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).
