The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Small Magellanic Cloud

Understand

We present OGLE-III Photometric Maps of the Small Magellanic Cloud.

• They contain precise, calibrated VI photometry of about 6.2 million stars from 41 OGLE-III fields in the SMC observed regularly in the years 2001-2008 and covering about 14 square degrees in the sky.
• Also precise astrometry of these objects is provided.
• One of the fields, SMC140, is centered on the 47 Tucanae Galactic globular cluster providing unique data on this object.
