CCD BV photometry of three unstudied open clusters: NGC 7044, King 2 and K11

CCD photometry on the BV system is presented for three, previously unstudied, rich open clusters. NGC 7044 is an intermediate age (t≅ 1.5 Gyr) cluster located at a distance of about 4 kpc. For King 2 the following limits on the age, reddening and an apparent distance moduli have been derived: 4≤t≤6 Gyr, 0.23≤E(B-V)≤0.50, 16.0≤(m-M)v≤15.0. The galactocentric distance of King 2 is equal to about 14 kpc. The age of K 11 is similar to that of M67 (5 Gyr). Its apparent distance moduli (m-M)v≅15.3. 13 refs., 8 figs., 3 tabs. (author)
