J/AJ/84/1305        UBV photometry in NGC 6528            (van den Bergh+, 1979)

The metal-rich globular cluster NGC 6528. van den Bergh S., Younger F. <Astron. J. 84, 1305 (1979)> =1979AJ.....84.1305V
ADC_Keywords: Clusters, globular ; Photometry, UBV Abstract: On the basis of its color-magnitude diagram NGC 6528 is one of the two most metal-rich globular clusters that have so far been found in the Galaxy. Such a conclusion is consistent with Morgan's metallic line-strength classification of the integrated spectrum of this cluster. The reddening of NGC 6528 is estimated to be E(B-V)=0.52±0.07, from which R=6.1kpc and Z=-0.4kpc.
