Hi, I have been testing on the mX analysis the Brehm recovery algorithm from Daniele and Ed. The result of the fit at the end of the machinery agrees within 2% with the result without Brehm recovery, with a stat error which is 12% as opposed to 13%: both efficiency and signal increase by ~10%. All other numbers are pretty stable. Detailed diff between result files is at the end of the mail. I will now start a production with all systematics configurations with VubAnalysis rf-042004 I think that for this iteration the best is that kerstin submits the signal jobs with the same tag and with the commands in http://www.slac.stanford.edu/BFROOT/www/Physics/Analysis/AWG/InclusiveSL/islrecoil/systRecipe/Rec.html ciao ric < Vub tot area = 2322.49 < Vcb tot area = 3357.13 < oth tot area = 337.533 < < Data 1' bin = 268.536 +- 20.3501 < Vub 1' bin = 1796.48 +- 47.0982 < Vcb 1' bin = 327.215 +- 21.8585 < Oth 1' bin = 43.5921 +- 7.97903 --- > Vub tot area = 2476.35 > Vcb tot area = 2716.34 > oth tot area = 278.087 > > Data 1' bin = 300.869 +- 21.3985 > Vub 1' bin = 1988.6 +- 50.7266 > Vcb 1' bin = 297.889 +- 18.934 > Oth 1' bin = 40.8574 +- 7.10509 48,50c48,50 < Vub comp = 0.0924542 +- 0.0129488 < Vcb comp = 0.293397 +- 0.0162559 < Oth comp = 0.151909 +- 0.102267 --- > Vub comp = 0.0921567 +- 0.0124523 > Vcb comp = 0.368912 +- 0.0203353 > Oth comp = 0.210026 +- 0.131059 53,55c53,55 < Vub fitted 1' bin = 165.91 +- 4.35442(stat MC) +- 21.3484(err fit) < Vcb fitted 1' bin = 96.004 +- 6.41323(stat MC) +- 5.31919(err fit) < oth fitted 1' bin = 6.62204 +- 1.21209(stat MC) +- 4.45805(err fit) --- > Vub fitted 1' bin = 182.393 +- 4.67479(stat MC) +- 22.6713(err fit) > Vcb fitted 1' bin = 109.895 +- 6.985(stat MC) +- 6.05767(err fit) > oth fitted 1' bin = 8.58113 +- 1.49226(stat MC) +- 5.35474(err fit) 57,58c57,58 < Vub 1' true = 2340.19 < Vcb 1' true = 3630.4 --- > Vub 1' true = 2490.17 > Vcb 1' true = 4207.31 62,69c62,69 < Vub total MC (lepton cut) = 7242.76 < Vub MC (all cuts) = 2322.49 < Vub MC (all cuts + Chop cut) = 1796.48 < Vub gene total MC (lepton cut) = 7242.76 < Vub gene MC (all cuts) = 2340.19 < Eps_u = 0.323107 +- 0.00549517 < Eps_Cut = 0.767662 +- 0.00873011 < Eps_tot = 0.248037 +- 0.00507463 --- > Vub total MC (lepton cut) = 7419.39 > Vub MC (all cuts) = 2476.35 > Vub MC (all cuts + Chop cut) = 1988.6 > Vub gene total MC (lepton cut) = 7419.39 > Vub gene MC (all cuts) = 2490.17 > Eps_u = 0.335631 +- 0.00548216 > Eps_Cut = 0.798578 +- 0.00803706 > Eps_tot = 0.268027 +- 0.00514225 74c74 < Nsl = 32173.9 --- > Nsl = 33346.3 76,78c76,78 < Nsl MC = 116060 < Nsl - BG = 108900 < (Nsl - BG)/Nsl (vub corrected) = 0.939234 --- > Nsl MC = 21579.6 > Nsl - BG = 20198 > (Nsl - BG)/Nsl (vub corrected) = 0.93694 83,84c83,84 < Eff on Vcb (Nvcb/(Nsl-BGsl)) = 0.0325946 +- 0.00180594 < Eff on other (other/(Nsl-BGsl)) = 0.00169677 +- 0.00114228 --- > Eff on Vcb (Nvcb/(Nsl-BGsl)) = 0.0320736 +- 0.00176797 > Eff on other (other/(Nsl-BGsl)) = 0.00186937 +- 0.00116651 87c87 < Nsig = 668.89 +- 86.0693 --- > Nsig = 680.502 +- 84.5857 90c90 < BRBR = 0.0196388 +- 0.00252701(stat) +- 0.000921929(MC stat) --- > BRBR = 0.0193245 +- 0.00240201(stat) +- 0.000902375(MC stat) 92c92 < Chi Square of the Fit = 0.651581 --- > Chi Square of the Fit = 0.656056
