Hi, Yesterday I committed a new multiplicity to centrality calibration for the 63 GeV AuAu runs. Djamel had noted that my previous calibration led to an increase in the centrality spectrum for more central events when the BB trigger was added in addition to the ZDC trigger, even if there was no downscaling of the ZDC. The previous calibration was based on the false assumption that the ZDC would be efficient for central events. The new calibration assumes the ZDC is efficient for those peripheral events where the tile multiplicity is >=4, but is NOT efficient for the more central events. I've put some details on the ZDC inefficiency at http://kunuc6.phsx.ukans.edu/~sanders/63GeV_Centrality/ CentCalibrationAt63GeV.ppt At this point there should be reasonably good year 2004 calibrations for both 200 GeV AuAu and 63 GeV AuAu corresponding to runs (200 GeV) 9389, 9701, (63 GeV) 11298, 11523. We will now start a systematic calibration of the other runs for 04.
