Hi, 1. We need to solve the fit problem observed in the mES fit on data with sl cuts. This fit has a problem with the Argus endpoint and complains about a non-positive error matrix due to the CB endpoint parameter. Antonio will try to fix this by forcing the fit to use only one endpoint parameter for the Argus and CB pdf. 2. We will meet aim for a phone meeting at 15:30 European time on Friday. Wolfgang, would this be ok for you? Cheers, Heiko
