Hi Mihajlo,
I have a quick question:
I generate 3 GeV photons using a single
track generator
c particle momentum theta phi delta_momentum delta_theta delta_phi
KINE 101 3.0 70. 0. 0. 0.001 360.
and obtain a 'strange' BCAL response; the total energy in the
event obtained by summing up DBCALMCResponse entries is
shifted by about +150MeV (see plot attached to this mail).
Do you know what the problem could be (do I miss smth, it seems that there
is no noise simulated here) ?
I checked out bcal reconstruction from a repository.
Thanks,
Sascha
