And indeed, that was the problem :-) I had only pushed back TPM2, not the entire array. After a day of fighting with geant (and hectic mailing with Flemming) the problem seems to be solved. The new acc files can be seen here: http://www.fys.uio.no/~bjornhs/brahms/ppAccProblem/ (bottom of the page) It now looks just like you'd expect - the data follow the acc. very nicely except for a few points that are just outside, wich is to be expected from the uncertainty in the vertex determination. Thanks again to Flemming and Kris :-) -- Bjorn H.
