Supplementary Notes

Terzan 3 is a low concentration cluster projected on the outskirts of
the Galactic bulge.  A near infra-red CM diagram (K, J-K) by Valenti et 
al. (2007) shows a red clumpy HB indicative of a moderately high
metallicity. They used their data to derive a photometric [Fe/H] =
-0.82. This is in good agreement with the value [Fe/H]= -0.75 that Cote
(1999) derived by measuring the equivalent width of an FeI spectral line
in a few red giants.
