Descripción
UBV, DDO and Washington photometric data for 14 red giant candidates of the open cluster NGC 2447 are presented. Membership results emerging from the application of two photometric criteria are in excellent agreement with those derived from published Coravel radial velocities. A mean cluster reddening E(B-V) = 0.05 + 0.04 is derived. Both the ultraviolet excesses and the cyanogen anomalies of the cluster giants imply [Fe/H] approximately -0.1. Five Washington abundance indicators yield a mean cluster metallicity of Fe/H]_W = -0.09 + 0.06, thus confirming NGC 2447 to be a slightly metal-poor open cluster.
