Hi Christian, I'm doing the development work on the new calibration in brahms_app/sjs_app/multCalib. Since the calibration relies on iterative fits of the actual data and corresponding geant simulations, I want to get the results needed for the current analysis out before working on getting the procedures incorporated into brat proper. I do agree that the basic calibrations should be transparent to the Collaboration and this is part of my motivation for consolidating the work in the multCalib directory. I have read the analysis note, but may have missed some subtlety: I still don't see how your procedure correctly handles the contamination of low-hit events or the varying background conditions for different locations in the array (see the PLB submission for some discussion of this). In any case, it would be interesting to see how your centrality determination compares to the one in the PLB submission. I will try to go over the analysis note again later this week while taking shifts at BNL. Good news about the database. Hopefully by next week we can start filling in calibrations for this years data. ...steve
