cds-question@unistra.frmagellanic-cloudssurveysinfrared-photometryvisible-astronomybroad-band-photometryWe present three color, BVI maps of the Small Magellanic Cloud. The maps contain precise photometric and astrometric data for about 2.2million stars from the central regions of the SMC bar covering ~2.4 square degrees on the sky. Mean brightness of stars is derived from observations collected in the course of the OGLE-II microlensing search from about 130, 30 and 15 measurements in the I, V and B-bands, respectively. Accuracy of the zero points of photometry is about 0.01mag, and astrometry 0.15arcsec (with possible systematic error up to 0.7arcsec). Color magnitude diagrams of observed fields are also presented. The maps of the SMC are the first from the series of similar maps covering other OGLE fields: LMC, Galactic bulge and Galactic disk. The data are very well suited for many projects, particularly for the SMC which has been neglected photometrically for years.1998AcA....48..147Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/48/147CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/244 : OGLE General Catalog of Stars.
