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
