VI Photometric Maps of OGLE-II Galactic Bulge Fields

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. See README file there for details.

Users of these data are kindly requested to send us a short note. Any comments about the data and the form of their presentation are also welcome as they can improve the future releases of photometric maps of other OGLE-II fields. Send your messages to this address.
