This directory contains the OGLE catalog of RR Lyrae stars identified
in the fields toward the Galactic bulge.
The directory structure is as follows:
README - this file
ident.dat - identification of stars
RRab.dat - parameters of RRab stars
RRc.dat - parameters of RRc stars
RRd.dat - parameters of RRd stars
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
gc.dat - candidates for objects located in globular clusters
pap.pdf - PDF version of the paper Soszynski et al. (2019),
Acta Astron. 69, 321, (arXiv:2001.00025) describing
the catalog.

Finding charts are gzipped Postscript images. The names of the files are in
the form: OGLE-BLG-RRLYR-NNNNN.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 RR Lyrae stars in the Galactic bulge should include the appropriate
reference(s) to OGLE paper(s).
