Hi Kerstin, both productions should be identical. In almost every aspect. Exceptions are the PID corrections and charged track efficiency corrections. They depend on random numbers. For the track efficiency I will look at some control histograms. The difference in number fo MC is only 0.13% for all MC and 0.09% for BB signal MC. Ahh, I have fixed on tcl file, which had some seriously broken events in it (50kevents at skim level. We have 2008/498 events more in the new production. From the additional file we get 1117/383 events. Still missing: 891/115 events. I can do some more checks in this. Both things shouldn't effect the data. Here the difference is 5x10-5. Maybe something to check. Cheers, Wolfgang On Fri, 12 May 2006, Kerstin Tackmann wrote: > > Hi Antonio, > > what about the fits prior to this change? Did you use the standard > selection as well?
