Results of the UPMASK run on the UBVRI data of Haffner 16. a) Distribution of all observed objects in positional space (X–Y CCD coordinates). b) Distribution of all observed objects in the V vs. (B − V) CMD. c) and d) Cluster membership probabilities are encoded as dot sizes and transparencies in the CMD and positional spaces (less probable = smaller and more transparent). e) and f) the same encoding, but for field membership probabilities.
