Abstract:

The accuracy of new charge-coupled-device CCD photometry in the Vilnius system of the M67 cluster is analyzed. The observational material was obtained during six observing runs in 1994 to 2001 with the 1-meter telescope of the U.S. Naval Observatory Flagstaff Station. The main task was to establish CCD standards of high accuracy and to eliminate large-scale errors from their CCD photometry. The authors compare their results with the published CCD photometric data in other photometric systems. The comparison reveals considerable systematic errors in some datasets. 4 figures, 3 refs.
