• hes code to fit all moments finished. He will do a mass dependent fit with a f0 and sigma.
• He has still not understood completely the problem of the ambiguity.

• she has rescaled the upstream ADC spectra and they lie on top of each other nicely. The matching has not worked so well fo the downstream end, but is trying to figure out what to do. They are shipping 2 modules from Jlab to IU for tests.

• needs more information on performance. Dave has gone through old reports and listing things that need to be added. He will send a list around before the work fest on June 3-4.

• He lookedd at optimum choices for the minimum γ energy cut.

• He has looked at E resolution in ω->π°γ and looked at the π°. The energy resolution from the π° band is systematically higher (worse) than the η. This is probably due to a contribution from the angular resolution.
