Hi Djamel, Apart from the, er, ummmm... non-optimal momentum performance... this looks really good. I think that even though the momentum has, er, ummm...issues, you can use this to get a first pbar over p, and K-/K+. It would be very interesting to finally see these numbers to compare with the 0.48 (y=2.1) and 0.27 (y=3). Also, have you checked a run with the opposite polarity (but same B, same angle) to see if the positives then have the lower mass2. Anyway, thanks for the nice plots, and good job with the calibration software (which is soon public?)!
