Abstract:
We present photometric maps based on data from the shallow survey in
the Large Magellanic Cloud performed as the supplementary project
during the third phase of the Optical Gravitational Lensing Experiment
(OGLE) . They cover about 40 square degrees in the LMC and contain
mean calibrated VI photometry and astrometry of about 1.7million
stars. The magnitudes of the objects range from 9.1 to 18.5.
