The intermediate age open cluster NGC 2660.

Abstract (from CDS):

We present CCD UBVI photometry of the intermediate old open cluster NGC 2660, covering from the red giant region to about seven magnitudes below the main sequence turn-off. Using the synthetic colour-magnitude diagram method, we estimate in a self-consistent way values for distance modulus [(m-M)0≃12.2], reddening [E(B-V)≃0.40], metallicity ([Fe/H] about solar) and age (τ≲1Gyr). A 30per cent population of binary stars turns out to be probably present.
