Hi, we are trying to use VubFit now. However, already our test fails to reproduce the result for |Vub| I find in BAD 540v9 while the branching ratio ratio is in agreement with what you give there. I get the following number: Vub(*10-3) = 4.49963 +- 0.274449(stat) +- 0.101763(MC stat) This is how I called VubFit: VubFit -Theosys -Mes mesparsetting.dat -F fit-p00 -D some_directory -C fits/subsetsTheo/s00.dat -s all -P s00_ I got copied the fit-p00 files from Urs, here is the contents: fileVubTotal /u/ec/ursl/root/anaQA-p00/csx-vubmix.root fileVubTotalres /u/ec/ursl/root/anaQA-p00/csx-vubmix.root fileVubTotalnres /u/ec/ursl/root/anaQA-p00/csx-vubnre.root fileVcb /u/ec/ursl/root/anaQA-p00/csx-genb-new.root fileData /u/ec/ursl/root/anaQA-p00/csx-data.root and for the first test I used those files. What should we do differently? Or are there any corrections that need to be applied for the results to be comparable? Thanks, Kerstin
