*** David is replacing the FMWPC clusterizer that was built into the DFMWPCMatchedTrack factory with the DFMWPCCluster class. Part of this includes adding x,y limits on the extent of the cluster to the DFMWPCCluster objects. These that can then be used to match the track projections. Placing DFMWPCCluster_factory consolidates the conversion from FMWPC coordinates to global lab coordinates in a single place.

* Need to add simulation code development to the agenda

** Andrew asked about if there was motivation for including kinfit info in his library other than for monitoring. (As opposed to holding it off until the final analysis). This led to a larger discussion on what plots will be needed for online monitoring.

** TAC runs (beginning and end only?)

*** Rory noted we will want invariant mass plots for e+/e- events and pi+/pi- events. We will want kinfit information for these if possible

** Empty Target

*** Some plots from the proposal that indicate polarization as measured using data from FMWPC detector

* Some question on e+e- generated events. Andrew noted that they are available on the work disk

*** Alex noted he is already working on adding plots to show residual position in FMWPC

−
*** Alex also noted the existing FMWPC_online plugin is intended for high statistics occupancy plots and we will want another plugin for the lower statistics plots that will require full tracking
+
−
*** Homework assignment for all to consider exact list of monitoring plots we would like in order to start working to get the required pieces to implement them.

*** David mentioned the possible use of Hydra for occupancy plots. Training on known possible failure modes in simulated data would be the best we could do for CPP since we don't have extensive beam data.
