Current Meeting:
21 August, 2012
     -(Johann) Update on Lambda cross section: This is almost 100% of g12 statistics of the Lambda events with beam energy corrections, momentum corrections, kinematic fitting (to exclusive p K+ pi- events), and fiducial cuts (as described in my dissertation -- assuming they are sufficient for the moment).
Ebeam for exclusive p K+ pi- events
invariant mass of p pi- for exclusive p K+ pi- events, showing Lambda(1115) cut (in brown).
Lambda yield (data. about 96% of g12 statistics)
     -The difficulty I'm currently facing is that I'm loosing about 12% of my generated events in the gsim/gpp/a1c tool-chain (they should have just passed through even if no track was reconstructed). I am running these programs interactively to determine which events were lost and to figure out how to recover them.
     -Finally, it seems I do not have the kinematic fitter properly calibrated for simulated data though Diane was successful in doing this (with my software) so this is probably something trivial I am overlooking.
