hi everyone,
  i went through the runs since yesterday morning and have calculated
the asymmetries. i used runs:

3200 3202-3206 3208 3209 3213-3215 3217 3220-3223 3225-3227 3229-3234
3239-3243 3246-3252 3254-3255 3257-3261 3263-3270

Scaler charge (Coulombs):
  pos helicity: 967.262
  neg helicity: 932.104
  total: 1899.35

  the cuts used were tdc[2][16][16] (timing), and pos[2][16][16]
(coplanarity), found in ~blast/commis/phase2/utils/cuts.C
  the cuts were created using data at full field, but should still be ok
at I=3000A, since the timing cuts were quite loose.

  the plot shows asymmetry vs. proton (y) and electron(x) paddle number
for protons on the left, and protons on the right. the asymmetry is
scaled by a factor of 10 (e.g. A_l_(14 prot, 2 elec) = +5% (proton on
left) )
