Abstract:
We present our catalog of U, B, V, and I stellar photometry of the
central 64deg2 area of the Large Magellanic Cloud. Internal and
external astrometric and photometric tests using existing optical
photometry (U, B, and V from Massey's bright star catalog (Cat.
II/236) and I from the near-infrared sky survey DENIS) are used to
confirm our observational uncertainty estimates. 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
Large Magellanic Cloud, confirm the variation of extinction as a
function of stellar population, and produce a simple geometric model
for the extinction as a function of stellar population.

Note (1): The flag values are additive. For example, a star with a flag value
of 11 has had its photometry replaced with that of Massey's (2002,
Cat. II/236) catalog and is fitted well with the atmospheric models.
0 = No flag
1 = Replaced with Massey's (2002, Cat. II/236) photometry and astrometry
10 = Colors successfully fitted with stellar atmosphere model
20 = Colors poorly fitted with stellar atmosphere model
