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

 *. Reconstructing on Pion

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();

*. Reconstructing Proton

*. Reconstructing Pion

4. Delta Vertex

 When reconstructed in Proton and pions it turns out to have the same ditreibutions so I just  posted one of them

5. Z Vertex and X vs Y vertex

6. Global Variables : Phi and  Rapidity

Reco Proton	Reco Pion

7. pt

8. Randomness
