Hi, I've managed to run with the right files and right conditions: here's the default: BRBR = 0.0169572 +- 0.00429294(stat) +- 0.00124563(MC stat) here's the value changed by the reweighting of k0 BRBR = 0.0166916 +- 0.00433252(stat) +- 0.00125693(MC stat) The effect is quite small (shift ~ -1.5%). Let me know if you want to do something else in this side. Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
