Hi,

 first of all happy New Year.


 As requested by Vera, I produced the results for the fitted
BR for b->clnu events.

 Here you can find all numbers for the different subsamples.
 The measured values are still ratios of branching ratios, but now
the expected result is 1.

 Actually it is not equal to 1 but to 1 - ratio(BR)_bulnu (since
in the numerator we have the b->clnu component while in the
denominator we have the total semileptonic BR). Then the expected
value is ~0.98.

All  BRBR = 0.931841 +- 0.055113(stat)

B0   BRBR = 0.931948 +- 0.101485(stat)
Bch  BRBR = 0.949709 +- 0.0652322(stat)
ele  BRBR = 0.914472 +- 0.0692768(stat)
mu   BRBR = 0.917701 +- 0.0837971(stat)
run1 BRBR = 1.0263 +- 0.0952589(stat)
run2 BRBR = 0.890657 +- 0.0607272(stat)
sb1  BRBR = 1.01698 +- 0.103764(stat)
sb2  BRBR = 0.985293 +- 0.0750252(stat)
sb3  BRBR = 0.86291 +- 0.0714007(stat)


depleted sample
---------------

All  BRBR = 0.947103 +- 0.0280162(stat)

B0   BRBR = 0.944411 +- 0.0562612(stat)
Bch  BRBR = 0.965159 +- 0.0328286(stat)
ele  BRBR = 0.9542 +- 0.0375441(stat)
mu   BRBR = 0.923164 +- 0.0381606(stat)
run1 BRBR = 1.01548 +- 0.0475409(stat)
run2 BRBR = 0.920063 +- 0.030727(stat)
sb1  BRBR = 0.968563 +- 0.060525(stat)
sb2  BRBR = 0.998408 +- 0.0395365(stat)
sb3  BRBR = 0.909976 +- 0.0380277(stat)



 I did not calculate the error due to the MC statistics but it
should be of the same order of magnitude of the statistical one.


 These results are in agreement with the expected values for all the
subsamples. This implies that the efficiencies on the background
are well estimated.
