1.0 MC Event Sample

1. Pythia event sample (pibero's gamma trees) w/ proper weighting for partonic pT bins
2. No offline trigger simulation
3. full EEMC acceptance

2.0 Definition of Isolation Cut

1. See Checking the isolation cut vs pythia events for definition of the 1-tower isolation cut and evaluation of rejection versus efficiency based on pythia events.
2. See Isolation cut, data vs. MC, take 3 for data vs MC comparison, including trigger simulation.

Geometry used in simulation/embedding for hits projection

For embedding with SSD, we project GEANT hits on real geometry.

 The following plots are for data.

In order to estimate the order magnitude of the single spin Collins asymmetry at midrapidity I calcuated the following partonic components from jet reconstruction using the STAR PYTHIA + GEANT simu

 The isolated BSMD cluster algo allows to select different range of tower energy cluster as shown in Fig.1

 these Gerber files  show the general routing for the top and bottom GEM foil layers plus a representative sample of the GE

I have looked at the new P08ic AuAu production that was done with Minuit3 VF to test Anthony's modified VF.
