P08id(ALambda -> P, Pion)

QA ALambda->P, pi (03 08 2009)

1. Dedx

Reconstruction on Proton and Pion Daugthers. 2 different plots are shown just for the sake of completenees....

Reco Proton	Reco Pion

2.Dca

An original 3D histogram had been created and filled with pT, Eta and DCA as the 3 coordinates. Projection on PtBins and EtaBins had been made to create this "matrix" of plots.

Pt Bin array used : { 0.5, 0.6, 0.8, 1.0} (moves down) and

Eta Bin array : {0.2, 0.5, 0.8, 1.0} (moves to the right)

For the Error bars, i used the option hist->Sumw2();

*.Reconstructing on Proton

3. Nfit

Similarly An Original 3D Histogram had been created with Pt, Eta and Nfit as coordinates. Respective projections had been made in the same pT and Eta Bins as the DCa distributions.

Pt Bin array used : { 0.5, 0.6, 0.8, 1.0} (moves down) and

Eta Bin array : {0.2, 0.5, 0.8, 1.0} (moves to the right)

For the Error bars, i used the option hist->Sumw2();
