Sartre 1.20 pAu 100x100 GeV

sigma(Au-src) = 956 nb
sigma(p-src)  = 831

Au-src, p-src mixed by cross sections,
for p-src=Au-tgt reject Au breakup (ZDC veto)

L = 1.75 pb^-1
efficeincies: STAR uptime 70%
	      J/Psi tracking & vertexing 50%
BR(J/Psi->ee) = 0.0594

Roman Pot: 0.03 < |t| < 0.3 (GeV/c)^2

Daughter electron pseudorapidities:
    both  -1 < eta < 2.2 (BEMC+EEMC)
 or both 2.8 < eta < 4 (FMS)

Cut on Au recoil pT:
  low Au-pt pT_Au^2 < 0.02 (GeV/c)^2 (enhance Au-src)
 high Au-pt pT_Au^2 > 0.02 (GeV/c)^2 (enhance p-src)

Events counts, from rapidity distributions:

 all Au-pt: Au-src 13k, p-src 1k
 low Au-pt: Au-src 13k, p-src 100
high Au-pt: Au-src  35, p-src 900
