dc.description.abstract | Photoelectric photometry in the UBV, DDO and Washington systems is
presented for 14 late-type giant candidates of the southern open cluster
NGC 2447. By applying two independent photometric criteria, nine stars
are found to have a high probability of being cluster giants. The
photometric membership results are in good agreement with those derived
from published Coravel radial velocities. The mean interstellar
reddening E<sub>B-V</sub> = 0.05±0.04 has been derived from the
confirmed cluster giants. NGC 2447 has a mean ultraviolet excess
<δ (U-B)> = 0.01±0.02 (σ <sub>n</sub>) with
respect to solar composition K giants, and a mean cyanogen anomaly
<Δ CN> = 0.01±0.02 (σ <sub>n</sub>), both
implying a small metal deficiency ([Fe/H] ≃ -0.1). Five independent
Washington abundance indices yield a mean cluster metallicity of [Fe/H]
= -0.09±0.06, in agreement with the two previous estimates.
Therefore, NGC 2447 is found to be slightly metal-poor. | |
