The Magellanic Clouds Photomtric Survey: The Small Magellanic Cloud Stellar Catalog and Extinction Map

Abstract

We present our catalog of U , B , V , and I stellar photometry of the central 18 deg 2 area of the Small Magellanic Cloud. We combine our data with the Two Micron All Sky Survey and Deep Near-Infrared Southern Sky Survey (DENIS) catalogs to provide, when available, U through K s data for stars. Internal and external astrometric and photometric tests using existing optical photometry ( U , B , and V from Massey's bright star catalog; B , V , and I from the microlensing database of OGLE; and I from the near-infrared sky survey DENIS) are used to determine the observational uncertainties and identify systematic errors. We fit stellar atmosphere models to the optical data to check the consistency of the photometry for individual stars across the passbands and to estimate the line-of-sight extinction. Finally, we use the estimated line-of-sight extinctions to produce an extinction map across the Small Magellanic Cloud, and we investigate the nature of extinction as a function of stellar population.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
