Minutes

    * Attending: Craig, Mike P x 2, William, Johann, Diane, John P.,
Sasha, Mukesh
    * Diane has made it through about 8000 files with gflux so far. The
farm is slow. Sasha reports the `-F' option to gflux makes Sasha's
answer off by a factor of 1000. Sasha will email Eugene about this
option and cc g12 at jlab.org. According to Diane's calculation we're
getting about 323 events per pb.
    * Mike P the postdoc showed his results from running the kinematic
fitter on his lepton data--basically he got nothing more out of the
fitter than what he would have got from his own kinematic cuts.
    * Craig showed some old plots from debugging the kinematic fitter for
use with the g11 momentum corrections. He'll have more to show next
week.
    * Craig also showed a fit to the omega in g12 data -- the tails don't
look so good. He'll try looking at a sum of two gaussians as a fit, as
well as a narrow W bin to see if it can be cleaned up.
    * Diane has about 95% of the data. After all cuts, she loses the a2,
and Sasha claims it was visible in g6c, without the 2gamma cut (see
link on the agenda)
    * Craig's currently occupied with momentum corrections and the omega
cross section so he hasn't made any progress on the charged 3pi.
    * Mukesh is busy working on the farm at FSU.
