[Hps-analysis] mad5VSdata!

[Sho Uemura]

Yes, the comparison is consistent. But changing to SVT momentum (and 
getting rid of the E(e-)+E(e+)<1.05 cut you have) will make the plots 
consistent with everyone else's.

Luca: The ECal energy is not completely corrected for edge effects (that 
is impossible). So the (large) fraction of pair events near the edges of 
the ECal often have ECal energies that are lower than the SVT momenta, so 
an Esum distribution made with the ECal will always be missing a lot of 
stuff at high Esum.

Maurik: Luca's plots do not have a tight fiducial cut. It is 55 mrad >= 
|theta_y| >= 15 mrad.
