=============================================
Terzan 2 is a metal rich core-collapsed cluster in a crowded field in
the Galactic bulge. 
VI photometry by Ortolani et al. (1997) illustrated that the cluster 
has a red HB in its CM diagram, but no information about blue stragglers
can be discerned because of the contamination by field stars.

No pulsating variables have been detected.  
------------------------------------------------------------------
There is a low-mass X-ray binary associated with the X-ray source in
Terzan 2.  Its properties have been discussed by in'tZand et al. (2007) 
and Altamirano et al. (2008).  No optical identification has been made
because the object is near the cluster centre where the crowding is
severe.
