A halo cluster of the LMC at 10 kpc: NGC 1841.
Abstract
The authors' conclusions from a comparison of the CMD of NGC 1841 with other Galactic and Magellanic globulars under the assumption that E(B-V) = 0.15 may be summarized as follows: (1) NGC 1841 is a very old, metal-poor globular cluster, closely similar to M92, (2) (B-V)0,g = 0.68, corresponding to [Fe/H] = -2.1, (3) from a fit to the CMD of M92, the authors find a true distance modulus to NGC 1841 of (m-M)0 = 18.1±0.3 (the currently favored distance of the LMC, (4) the luminosity discrepancy between the NGC 1841 giants and those of, e.g. M92, is removed.
