Hi Urs, some comments on your XXXs > FROM ECKHARD > http://www.slac.stanford.edu/~ursl/fsx/commentsToPapers/b2u/elsen.1 > p1, ?4: We eliminate events with low purity... To remove possible > confusion: We exclude events in which this purity P is low. why not? > p2, ?2: - tracking and calorimetry details: With the curlers and energy > deposits mentioned here after the B-reco one starts to wonder how the > Breco would have been affected had the tracks been removed in the first > place. - My feeling is that this is too much detail. we basically remove duplicates also from Breco since we do the overlap also with the breco.
