Other observations include the broadening of the 4th layer and the spread of the 1st layer to smaller z values.  David reminded us that the field near the outer layers has a radial component.

    1. Andrei & Irina: Andrei presented the simulations from the single-module standalone MC, showing the energy deposition centroids. Two observations are apparent: a) as theta decreases from 90 deg, the centroid loci for the triple and quadruple layers deviated significantly from the direction of the incoming photons and b) even though the 3rd and 4th row clusters are not on the line, they belong to the event so they their energy needs to be accounted for, although they should not be used untreated to define the photon path through the layers. Other observations include the broadening of the 4th layer and the spread of the 1st layer to smaller z values. David reminded us that the field near the outer layers has a radial component. Zisis mentioned that the 2006 beam tests may not have many events in the rear layers sine the tagger energy went up only to 650 MeV.
    2. Will compared the KLOE and IU codes.
Discuss and prioritize the Reconstruction Issues and produce a timetable for the work.
