Dear all, I realize this list has not been used much during the last time, but I am hoping that someone has answers to two questions. I remember that there was an issue with forcing consistent random number seeds between the default production and the productions we run for the systematics. Can anyone point me to where and how this is exactly done in the code? I think this is relevant for the tracking and the neutral systematics, but not the PID systematics (which somehow take care of that themselves according to comments on the PID page). Is that correct? Thanks! I see in VubXlnu.cc that there is some "pi0 killing" going on when the kinematic variables for the soft pi- partial D* reco are computed (killing as in they are not computed for every pi0). This killing probability is a function of the soft pi0 momentum. Why is this done and where do the parameter (and the parametrization) of this function come from? Thanks a lot for any help I can get on either of the two questions! All the best, Kerstin
