Hi all,

 I took the root files produced by Urs with different seeds for K PID (I
think it is only K ID) and I ran the fit on them.

 I noticed that Urs ran on the 160 fb-1 MC and not on the full sample but
who cares.

 This is the result

 default
 BRBR = 0.0202685 +- 0.00250473(stat) +- 0.00106675(MC stat)
 4 different seeds
 BRBR = 0.0199513 +- 0.00250629(stat) +- 0.00108934(MC stat)
 BRBR = 0.0206593 +- 0.00250784(stat) +- 0.00108017(MC stat)
 BRBR = 0.0200895 +- 0.00249793(stat) +- 0.00109631(MC stat)
 BRBR = 0.0199593 +- 0.0025139(stat) +- 0.00111451(MC stat)

 One of the tests gave NaN because the data file was not there.

 I looks like we are not in a tail of the distribution even if, I must
admit, we statistics is pretty poor.

 I would say that the test is very successful.
