Abstract
UBV photoelectric photometry for 204 stars in the field of the souther n open cluster IC 2714, supplemented by DDO and Washington photometry and Coravel radial velocities of 14 probable red giants, are presented . The analysis of the photometric and kinematical data yielded 132 pro bable members and 13 possible members. IC 2714 contains one variable s tar and 11 red giant members, one of them being a spectroscopic binary . Two red giants are either binaries or non-members. The reddening acr oss the cluster is slightly variable, the mean value is E(B - V) = 0.3 6. The cluster distance-modulus is 11.68, corresponding to a distance of 1320 (+/- 120) pc and the mean radial velocity is -14.1 +/- 0.3 km s(-1). The age, determined by fitting isochrones with core overshootin g, turned out to be log t = 8.5, corresponding to 3.2 10(8) yr. A meta l abundance [Fe/H] = -0.12 +/- 0.09 relative to the Sun and other fund amental parameters are determined. The luminosity function of the brig ht members of IC 2714 is in good agreement with that determined by Taf f (1974).
