Hi, running the banapp software: dst2tree generates a generous amount of diagnostic histograms. Some I've found particulary usefull are the average number of tracks pr X events. Other usefull ones are looking at the track distributions on the detector planes (perpendicular to the detector z-axis)... Ratio of scaled trigger 1 and trigger 4... Yields on run by run basis are also good (making ratio with the total average)... comparing yields from different vertex bins... Most (all?) of the histograms should be made both on run by run basis and all runs combined by the selector classes. There could be added more, but I've currently ran out of ideas... Check and test and come with more suggestions...
