Hi, JH noted yesterday on another distribution that there were a large number of dAu runs with bad centrality calibrations. In tracking this down, we find that the SiMA clearly went into noise oscillations a number of times during the experiment. This had already been known to have occurred at the end of the dAu runs, when the array was finally turned off, but until JH's check, we missed the earlier problems. Today I asked Brett to go back over the runs in range that JH had scanned to look for bad SiMA runs. He found a total of 24 bad runs (see his note below). I have added a check in the BrMultCentModule to set the "average mult" equal to the TMA multiplicity for the centrality analysis of these runs. The final centrality looks reasonable, as shown below for run 8458 (trig 5). ...steve Begin forwarded message: > From: Brett Neumann <bneuma@ku.edu> > Date: Tue Nov 18, 2003 4:11:22 PM America/Winnipeg > To: "Stephen J.
