L3BhaVeto2Pr ) & ( ! L3BeamGas ) Comments on the Bhabhas: The terms "fiducial" and "non-fiducial" may be a bit confusing here, so I offer the following for clarification. In the "non-fiducial" sample, we look at all bhabhas except those that don't produce visible energy. In the "fiducial" sample, we divide the bhabhas into categories based on the number of leptons inside the calorimeter volume and the presence of radiated photons. (Specific definitions were provided earlier by Ed.) In all cases, the first number in the Nevt column represents the number of events that fit into the specified category. The number in parenthesis below it is the total number of bhabha events that were processed in order to obtain these events. Events not counted in "Nevt" are not counted in any other column.
