Abstract:
We present new photometric data for 14 galactic open clusters taken by
the 65cm telescope at Gunma Astronomical Observatory. They were in the
anti-galactic center region selected from the Catalog of Open Cluster
Data (Lynga, 1987, See Cat. J/A+A/438/1163). We estimated the
parameters of the clusters, i.e., age, metallicity, distance, and
reddening, by fitting Padova isochrones to the color-magnitude
diagram.
Description:
The data were collected with the 65cm telescope at the Gunma
Astronomical Observatory, equipped with a CCD camera. Standard Bessell
B, V and I filters (Bessell, 1990PASP..102.1181B 1990PASP..102.1181B) were used, and the
magnitudes of the stars were transformed into the Johnson-Cousins
system.
