Kiyoung's talk: see the slides for more details. (2 configurations in the study: UV and XY)
UV layers and XY layers’ reco percentage: UV: 10%, XY: 6%.
Charge ID total accuracy: XY: 81.3% , UV: 82.4%.
Stopping power: volume cut: Z: two planes from the back, X, Y plane: 73 mm.
efficiency = (True stop) / ( True stop + False exit ), as volume cut gets tighter false exit gets larger, efficiency is decreased.
Momentum from the Kalman filter doesn't work well for UV.
Summary: charge ID from UV is slightly better than XY. Stopping power depends on volume cut and XY is better than UV.
