Hi, I'm currently looking at the high field Au+Au runs and I'm having some trouble at the edges of the acceptance - the data is not right on the MC so I started looking at the magnetic field. Is it correct that we still use the (2nd order) parametrization of the field? I've compared the field I get from BRAT and what has been measured (By) with the Hall probe and there is a small discrepancy which I guess would effect the high field data the most. Have a look: www.nbi.dk/~ekman/fieldVsCurrent.gif Putting the numbers directly in BrMagnetVolume would be very easy, but I guess that's not good enough. Do we want to store this information in the DB? And what does it take? I think it's pretty important if we want to make a good analysis of the high field data...
