Hi all,

 I repeated the fit using Mx instead of the fitted Mx.

 These are the results:


 Q=0

 All
   BRBR = 0.0175419 +- 0.00407794(stat) +- 0.00118571(MC stat)
   chi2=0.883673

 B0
   BRBR = 0.00401112 +- 0.00680338(stat) +- 0.0019864(MC stat)
   chi2=0.994055

 Bch
   BRBR = 0.0264318 +- 0.00509347(stat) +- 0.00171483(MC stat)
   chi2=1.66344



 Q=1

 All
   BRBR = 0.0254868 +- 0.00452458(stat) +- 0.00137868(MC stat)
   chi2=0.891207

 B0
   BRBR = 0.0142957 +- 0.00719002(stat) +- 0.00221697(MC stat)
   chi2=1.20538

 Bch
   BRBR = 0.0332868 +- 0.00586739(stat) +- 0.00192195(MC stat)
   chi2=0.607417


 The results are perfectly in agreement with the ones obtained
with mxhadfit (compare with the table in the BAD). The errors are of the
same order. You can comment the chi square by yourself.
