PALOMAR 10 AND NGC 6749: A STUDY IN CONTRASTS
Abstract
We present new photometry in V and I for Palomar 10 and NGC 6749, two heavily obscured and sparse globular clusters. The color-magnitude diagram (CMD) of Pal 10 exhibits marked differential reddening with a mean reddening E(B-V) = 1.66 ± 0.1. Its CMD has the purely red horizontal branch characteristic of a high-metallicity cluster; we estimate [Fe/H] ∼ -0.1 on the Zinn-West metallicity scale. NGC 6749 (= Berkeley 42, listed in some other …
