Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

Abstract:
We present the VI photometric maps of the Galactic bulge. They contain
VI photometry and astrometry of about 30 million stars from 49 fields
of 0.225 square degree each in the Galactic center region. The data
were collected during the second phase of the OGLE microlensing
project. We discuss the accuracy of data and present color-magnitude
diagrams of selected fields observed by OGLE in the Galactic bulge.
The VI maps of the Galactic bulge are accessible electronically for
the astronomical community from the OGLE Internet archive
