+     - Changed upper limit of hadronness histograms from 1. to 1.0001.
+       Before, events with hadronness=1 were put in the overflow bin,
+       and they were not counted in the calculation of hadron efficiency
+       or of the quality factors that were displayed in the plots and 
+       on the text messages. At high energies the underestimation of Q
+       could be as large as a 20%.
