DDO photometry of giants in four southern open clusters
Results are presented for photoelectric photometry in the DDOintermediate-band system of G and K giants in the very old open clusterMelotte 66 and the old clusters NGC 4349, 5822, and 5823. Averagereddenings, corrected mean distance moduli, and mean cyanogen anomaliesare derived for the giants in these clusters, and several peculiar starsare identified. The results indicate that: (1) the giants in Melotte 66are deficient in CN (and therefore in metallicity) relative to nearby Kgiants; (2) there is no evidence for a change in overall CN strengthbetween the giant and horizontal branches of Melotte 66; (3) NGC 4349and 5822 appear slightly richer in metals than nearby K giants; (4) NGC5823 does not constitute a coherent sample of giants and is likely to beaffected by considerable field-star contamination; and (5) there is onlymarginal evidence for a physical association between NGC 5822 and 5823.
