J/PASJ/56/295       BVIc photometry of old open clusters     (Hasegawa+, 2004)

New photometric data of old open clusters in the anti-galactic center region. Hasegawa T., Malasan H.L., Kawakita H., Obayashi H., Kurabayashi T., Nakai T., Hyakkai M., Arimoto N. <Publ. Astron. Soc. Jap., 56, 295-311 (2004)> =2004PASJ...56..295H
ADC_Keywords: Clusters, open ; Photometry, UBVRI Keywords: Galaxy: evolution - Galaxy: open clusters and associations: general - Galaxy: structure - ISM: extinction 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) were used, and the magnitudes of the stars were transformed into the Johnson-Cousins system. File Summary:
