Angular resolution with high energy electrons (see Nicola's talk given at teh EVO meeting on Jul, 18 2007):
The angle has been evaluated with respect to the nominal beam direction bu using the first track directions. The angle distributions look like gassian, then they are fitted with a gaus function to evaluate the peak value (MPV) and the sigma value. These results are preliminary, since the CU needs to be better aligned with to respect the beam directions .
