Abstract:
CCD photometry in the VRI and Gunn z bands was obtained for the
populous bulge globular cluster NGC 6356. The analysis of the red
giant branch indicates that it is metal-rich, intermediate between 47
Tuc and NGC 6528; we estimate [Fe/H]≃-0.4. The red giant clump is
clearly detected. The horizontal branch morphology is red and compact.
We derive a reddening of E(B-V)=0.2410.04 and a distance d=15.010.4kpc
from the Sun. We also present VI colour magnitude diagrams of 47 Tuc
for comparison. NGC 6356 and 47 Tuc are important reference objects
for studies of more reddened metal-rich bulge clusters.
