Hi all, During some analyses, I had to determine track matching offsets in the MRS and FFS (BFS is on its way) for a big bunch of runs. In order not to get bored, I made a script to do it fast. You can check the result here: http://www.nbi.dk/~ouerdane/match You will notice some funny behaviours in dY and dAng as a function of run number. The FFS tracking shows that it's fairly stable, despite a few jumps (I checked the histograms and it really did that!) The MRS is not as stable. Notice also how dAng goes to zero for the later runs (after 5730). Of course, these runs have different field settings and background conditions. But it's nice to see the behaviour of these offsets over this long period of time.
