Photometric study of open clusters Berkeley 96, Berkeley 97, King 12,
  NGC 7261, NGC 7296, and NGC 7788
  The BVRcIc CCD photometry in the fields of six open clusters toward the
Perseus spiral arm is presented. These data along with JHKs magnitudes taken
from 2MASS catalog, have been used to determine cluster's ages, distances and
color excesses. In addition, the gaps in mass function of Be 97, King 12 and
NGC 7788 clusters have been revealed in mass intervals of 1.3-1.5, 1.4-1.6 and
1.5-1.7 solar masses, respectively.
