keyword=better Q2While waiting for beam studies, I checked the Q2 some
more. The run database was quite wrong. I put in the correct
momentum settings, and for the beam energy I put E_beam - < x*dE/dx >.
This leaves the L-arm missing mass shifted by 5 MeV while for the
R-arm the missing mass happens to be perfect. The 5 MeV shift
could be a momentum scale problem (of order 0.1%) or something else.
