I ran the gamma maker in the endcap over the data.  There is not trigger or isolation requirement applied to the candidates so these are mostly pions and etas. 

Plots below are of energy deposited in various layers, along with basic shower shapes and isolation.  The only maybe strange thing is the smd v-plane shower shape.  However, it looks like there was a slight fluctuation in the number of v-strips that would give more v-plane strips than u-plane strips so the fluctuation in the tail of the shower shape is probably just statistics.

FYI: shower shape defintition = energy deposited in strip i/total energy in the plane.  The maximum energy strip is always plotted at 11 and then you have +/-10 strips on either side.
