The open cluster NGC 2204.
Abstract
Photoelectric photometry in the intermediate-band DDO system and the wideband Cousins VRI system is presented for representative giants in the old open cluster NGC 2204. The metal-poor character of the cluster, suggested by previous UBV photometry, is confirmed and an average cyanogen anomaly of -0.047 + or - 0.009 mag (m.e.) is derived. There are several stars in NGC 2204 which may have unusual surface compositions.
