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
