Note that the track of the electron in the calorimeter does not have the "holes" showed for the muon events from runs 460 and 322. Images ElectronWithCU_2_ZX ElectronWithCU_2_ZX ZY show the second electron event from the ZX and ZY perspective. The track is well defined in both planes.
The distributions of the variables Trk1ZDir and CalZDir are shown in Electron811Reconstruction.gif, Electron811Reconstruction.ps and Electron811Reconstruction.root (gif, ps and root files). And the distribution of the variable CalTransRms is shown in Electron811CalTransRms.gif, Electron811CalTransRms.ps and ElectronCalTransRms.root. Note that the reconstruction fo these variables is not as "incorrect" as in the case muons events from runs 460.
