Reconstruction sub-group reports
Calorimeters
Matt gave the report.
- Will has checked in changes to BCAL code
- When there is a demonstration of improvement with the new code versus the legacy KLOE code, the new code will be made the default.
Tracking
Simon and Will gave reports.
Simon reminded us that problems have been reported with the proton reconstruction efficiency in events. A couple of rounds of improvements have been tried, with modest gains. Work on this continues.
In the light of recent improvements, Will has started looking at reconstruction efficiency and kinematic fitting for all-charged-final-state events. See his wiki page for details. He is seeing relatively high reconstruction efficiency, but not so good efficiency for passing a confidence level cut. Several people suggested restructuring the study to separate the effects of reconstruction and those of the calculation of errors.
