Description
UBVI CCD photometry has been obtained for the intermediate-age open cluster M35 (NGC 2168). From this new photometry we derived the cluster parameters (Vo-MV= 9.60+/-0.10 mag, E(B-V) = 0.255+/-0.024 mag), age (logAge=8.3+/-0.3) and a photometric abundance (Z~0.008, i.e. [Fe/H]~-0.3) from comparison with theoretical isochrones of the Padova group. A minimum binary frequency (35+/-5%) was estimated from the distribution of distance moduli of unevolved proper motion members. Faint photometric members were selected by using differences in the reddening effect on colour indices.
