1. 1 task for training on 08.01.2009 (1/3) 1. Copy the root file containing tree (run10302-1.root) and script./create_maps/MapEfficiency.C into your local working place. 2. locally, open the file in the interactive root session and observe content of the by using TBrowser class a) inspect content of directory BBVertex b) inspect content of directory Tracking_BFS c) inspect content of directory Efficiency (which documents a performance banapp EfficiencyFinderModule) and find a tree named MyTree. Browse a structure of the tree (branches and leafs). Plot A distribution of the particular leaf (variable).

2. 2 task for training on 08/15.01.2009 (2/3) 3. edit the file MapEfficiency.C 4. modify its content, so, it will plot efficiency for one (requested) chamber only versus the requested variables (indications: remove MapAll(...) method and use only MapEfficiency(...) which creates maps for one detector. Modify accordingly the method GetRunArray(...) to account for run 10302. If you are lost ask an expert for help). 5. modify the content of MapEfficiency.C, so, it will plot integrated efficiency versus sigma range (cut size on matching parameters). (indications: add an extra 1D histogram. Create and fill it in the method GetHisto(...). Modify accordingly methods GetEfficiency(...)and MapEfficiency(...)) 6. plot efficiency versus sigma range counting every local tracks in the cut window. Compare results with the one tracks method

3. 3 task for training on 08/15.01.2009 (3/3) 7. plot the dependencies (on sigma range) for 0-40% central events and for 40-100% central events. Compare and interpret the obtained results. 8. plot the dependencies for low momentum and high momentum reference tracks. Compare and interpret the obtained results.
