VizieR Online Data Catalog: UBVI photometry in NGC 6752 (Kravtsov+, 2014)
Abstract
The observations were acquired on three nights (1999 October 13, 15, and 17) with the 1.3m Warsaw telescope at Las Campanas Observatory using a set of UBVI filters and a 2048*2048 CCD camera with a gain of 3.8 and a readout noise of 5.5e- rms. The scale was 0.417''/pixel, giving a field of view of 14'*14'. The center of the measured field of NGC6752 was approximately 30'' to the east and 30'' to the south of the cluster center. The average seeing on each night (FWHM), estimated from the observations, was in the range of slightly subarcsecond to 1.5'', 1.3''-1.9'', and 1.4''-2.7'' on the three consecutive nights, respectively.
The instrumental magnitudes and colors (v, u-b, b-v, v-i) obtained for the measured stars were then transformed to the standard system (V, U-B, B-V, V-I) The obtained photometric data are given in Table2. (1 data file).- Publication:
