Abstract:
We present for the first time optical colour magnitude diagrams of the
globular cluster Terzan 2, in the V, I colours. The horizontal branch
is red. The red giant branch morphology can be fitted with that of 47
Tuc, but definitely not th at of NGC 6553. We derive a reddening of
E(B-V)=1.54 and a distance d☉=7.7kpc if R=3.1, or 5.3kpc if
R=3.6. Terzan 2 adds to the list of bulge metal-rich
clusters now with reliable parameters.
