All right, you gave the answer!! The calibration between run 3995 to 5326 are simply wrong since they used some other slewing fits, therefore all your times are wrong. I never had the time to redo these calibrations with the latest software. In fact, I even suspect that you pick up the old calibration (that was stored into the DB for testing), used with the newest software and calibration procedure. And in this case, there's a slewing parameter that does not exist. And it's not only that: the old calibration deals with TDC in units of channels, the new with TDC in ns since the TDC gains are not exactly at 25ps/chan. If you for ex. analyze run 3994 or 5326, you should have correct result. One has to redo the calibrations for the intermediate runs. And this point calls the one raised by Christian about calibration shift :) Ciao Djam -- Djamel Ouerdane ------------------------------------------o | Niels Bohr Intstitute | Home: | | Blegdamsvej 17, DK-2100 Ø | Jagtvej 141 2D, | | Fax: +45 35 32 50 16 | DK-2200 Copenhagen N | | Tel: +45 35 32 52 69 | +45 35 86 19 74 | | http://www.nbi.dk/~ouerdane | | ouerdane@nbi.dk | o---------------------------------------------------------o
