my point was the following: these events (I mean nle=1 and nchg=nneu=0)
could be used to perform the unfolding and can reduce the stat error
on the unfolding itself. It is just a matter of adding another category.
In principle there is no reason why we should not use it in the BRBR
extraction as well. We should just check the S/B for those events.
Am I wrong?
