==Minutes==
* In attendance: Dennis, Mike P., Diane, William, Carlos, Craig, Paul E.,
Miles, Sasha O., Mukesh
* Cooking update: pass1 complete, 57,000 files in on /mss (90%)
* Paul needs slides for a status update that Volker Burkert requested--he
plans on poaching slides from Hadron09, but for e+e-, pentaquark, etc, he
needs slides.
* Sasha reports that the gflux executeable is operational but he needs
100% of files for a run to do the number of photons per run, and the
number of runs with 100% of files succesfully cooked is pretty low, so
that is slowing us down.
* Paul would like there to be a standard set of g12 cuts for cuts that are
common to all analyses; like the st_vtime - vtime cut, for example. Dennis
agrees that this will be necessary down the line but at the moment we're
not ready.
* Craig will contact Heghine and get her to give an update next week about
the momentum corrections.
* Craig will email Gagik/Valery and ask him what he does to correct for
the tagger sag.
* Mike presents some of his results from e+e- and there is much
discussion, especially regarding the missing mass off the proton spectrum,
which has all kinds of unidentified bumps. It remains difficult to
separate the Dalitz decays from the pure e+e- decays.
* Craig reports that the start counter is 98.5% efficient integrating over
all paddles.
