X-ray of material in front of STAR EEMC using pi0s for 2006, 2009, and some MC

A method of determining the number of radiation lengths of material between vertex and the EEMC as a function of position by using pi0s, and isolated towers and preshower 1 appears to work well.

Azimuthal Angle Studies

When using the simple ("Mickey Mouse") MC generator and y2006h geometry to produce single photons in a very small pT, eta and phi domain, a strange pattern was observed in the number of pairs meeting neutral pion cuts.  The following are some plots to the related study.  This was a combined effort of myself and Hal Spinka.
