CCD BV photometry of three unstudied open clusters : NGC 7044, King 2and K 11.
Abstract
Results are reported from photometric observations of three rich open clusters, obtained using CCD cameras 1 and 3 on the 1.09-m telescope at KPNO in December 1986. The data are presented in extensive tables and graphs and characterized in detail. The approximate age, reddening, and apparent distance modulus are found to be 1.5 Gyr, 0.74, and 15.3 mag for NGC 7044 and 4-6 Gyr, 0.23-0.50, and 15.0-16.0 mag for King 2; the age and apparent distance modulus of K11 are given as 5 Gyr and 15.3 mag.
