Hello,
I changed in svn the geometry of the EMC, shifting the barrel of +37mm as it shpuld be according to the design of the last integration TAG meeting:

index.php?t=getfile&id=3539&private=0

In this way all the crystals will not point toward the interaction point, so that we do not have the hole in efficiency at 90°.

Meanwhile I added in CbmEmcPoint and in CbmEmcHit the member functions GetTheta() and GetPhi(), which provide the polar and azimuthal angles in the lab system (different from fTheta and fPhi).
