Abstract

We present BVRcIc CCD photometry in the fields of six Galactic open clusters toward the Perseus spiral arm. These data, complemented with J, H and KS magnitudes from 2MASS, have been used to determine the following ages, distances and colour excesses E(B − V) for these clusters: 40 Myr, 3180−380+440 pc, 0.54 ± 0.03 mag (Berkeley 96); 250 Myr, 2410−200+220 pc, 0.77 ± 0.06 mag (Berkeley 97); 70 Myr, 2490−170+180 pc, 0.51 ± 0.05 mag (King 12); 160 Myr, 2830−150+160 pc, 0.88 ± 0.09 mag (NGC 7261); 280 Myr, 2450−170+190 pc, 0.24 ± 0.03 mag (NGC 7296); 160 Myr, 2750−210+220 pc, 0.49 ± 0.02 mag (NGC 7788). We found gaps in the mass function of clusters Be 97, King 12 and NGC 7788 in the mass intervals [1.3–1.5], [1.4–1.6] and [1.5–1.7] solar masses, respectively.
