Hi,
I did changes in the fit. The main points are (the ones that
actually affect the final number):
1) the efficiency for the signal is now calculated on the generic MC and
the value is 13% lower than the one on the cocktail.
2) the ratio factor eps_u^l/eps_sl^l is now calculated directly in the
fit and not fixed (as before). This is more coherent when you perform
stability check and breakdowns. The value now is ~3% up then before =>
shift up in the reult of ~3%.
For the remaining important (but not crucial) changes I just append to
the mail the message of my commit.
Tomorrow I will redo all the fits already in the BAD and I will post
them.
Cheers,
Daniele
