Any idea what is wrong with right sector protons
and the vertex distribution (red-prot, green-elec)?
I'm in the process of finalizing a kinematic
corrections algorithm. It is a 2D X^2 minimization
where I will reproduce the Beam Energy predicted by
Monte Carlo. Once the proper momentum and theta agree,
I will compare the Q^2 calculations from each particle's
respective momentum and theta and then iterate depending
on the discrepancy.
I'm trying to do this with separate combinations of
adding energy loss and disregarding energy loss. If
the process works correctly, I assume that the offset
difference should reproduce the the energy loss
parameterization.
Next, I'll do a new 2005 GEN analysis with new crunch
and electron corrections.
