Hello. If you want an official fully analyized number, I don't think you will get it in the next week (or probably not next month). This requires running full geant simulation and complete calibration in our data. I am not sure if we have either one of them. And, anyway, the method I described will gives you very good number (within a few percent, which is far better than our systematic error). Hiro Claus O. E.
