Extract

This cluster has two notable characteristics: it contains more than 80 variables, and relative to its NP half its SF half is covered by a cloud absorbing up to a magnitude in the blue. These properties make it an ideal object for determining the ratio Av/E of V absorption to colour excess—one simply compares mean colours and magnitudes of variables in the obscured part with those in the clear part.
