Hi guys, This is correct: when computing the error from the resonant states, I increased the number of non-resonant states to keep the total B->Xulnu BF set to the nominal value. Hence, you will have to apply an additional weight on top of the hybrid weights to get the right contribution from non-resonant. Cheers, Dominique > That is not the case unfortunately.
