Abstract (from CDS):

BV photometry of the faint open clusters Berkeley 36, Berkeley 73 and Biurakan 13 are studied. For these clusters no colour-magnitude analyses were previously available. The colour-magnitude Diagrams indicate that they are all old open clusters. The derived ages are ∼4Gyr for Berkeley 36, and ∼2.3Gyr for both Berkeley 73 and Biurakan 13. The clusters are not very reddened, with E(B-V)=0.25, 0.10 and 0.30 respectively for Berkeley 36, Berkeley 73 and Biurakan 13. Berkeley 36 and Berkeley 73 are located at a distance from the Galactic center of ∼10kpc, while Biurakan 13 is much farther, at 15kpc. A peak in the age distribution appears at 5Gyr suggesting a distinct star forming event in the disk.
