Scientific paper

UBV photoelectric photometry for 204 stars in the field of the southern 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 probable members and 13 possible members. IC 2714 contains one variable star and 11 red giant members, one of them being a spectroscopic binary. Two red giants are either binaries or non-members. The reddening across the cluster is slightly variable, the mean value is E(B-V)=0.36. The cluster distance-modulus is 11.68, corresponding to a distance of 1320(+/-120)pc and the mean radial velocity is -14.1+/-0.3km/s. The age, determined by fitting isochrones with core overshooting, turned out to be log t=8.5, corresponding to 3.2x10^8^yr. A metal abundance [Fe/H]=-0.12+/-0.09 relative to the Sun and other fundamental parameters are determined. The luminosity function of the bright members of IC 2714 is in good agreement with that determined by Taff (1974).
