Room: CERN 14-4-030

Please bring your laptop.

The slides of todays lecture can be found here.

Who: Prof. Arno Heister

Room: CERN 354-1-016

Please bring your laptop. We will continue working with the jet event example in the ROOT tutorial section today.

Here is a link to the slides for today: CMS PAT introduction

Links for todays lecture:

1. CMS computing model
2. How to locate CMS data
3. CMS data analysis school (prelimenaries)

Homework:

• Pick one or more exercises from here.

Who: Prof. Arno Heister

Room: CERN 354-1-016

Please bring your laptop. We will work with the jet event example in the ROOT tutorial section today.

Homework:

• Upgrade the jets.C TTree loop and add the option of filling histograms with info from the JetEvent class. Also add the possibility to cut on quantities like e.g. the number of tracks per event, the pt of jets, etc. Upload your work i.e. .C files, etc. as usual before the next lecture to this area. Important: Do not use anywhere the SetBinContent method.

Who: Prof. Arno Heister

Room: CERN 354-1-016

Please bring your laptop. The slides can be found here.

Homework:

• Compute a 1-dim histogram containing a poisson distribution. Then fit to this histogram other distributions, e.g. polynoms, a Gaussian distribution, Poisson …, etc. Try to understand how much like a polynom, gaussian, etc. the distributions look like as discussed in the lecture today. You can use as template the fillrandom.C example which can be found in the ROOT tutorials area. Upload the .C file with the poisson histogram and fit before the next lecture to this area.
• Check out more ROOT tutorials, e.g. $ROOTSYS/tutorials/spectrum/peaks.C. Try to give an argument like $ROOTSYS/tutorials/spectrum/peaks.C(3) corresponding to computing 3 peaks.
