1. asymmetry for different acceptance cut
Pengjia Zhu

2. dp y
acceptance cut variables in target plane coordinate:
L.rec.dp
L.rec.y directly from bpm info
L.rec.theta
L.rec.phi
theta
phi
accumulate from a bunch of runs
Runs used:
2.5T longitudinal
Run Status=1
Run Quality>0
NH3 target with Material 17
dilution factor used: 0.15
