LHC software course: ROOT introduction

CMSAEP, Events

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.

Who: Prof. Arno Heister

Room: CERN 354-1-016

Today we have the 2nd session of students’ presentations. The slides will be available shortly after the meeting starts from here.

Please bring your laptop.

Homework:

  • Update your presentations with details from the discussions afterwards and upload them again.
  • Find out details about Binomial, Poisson and Gaussian distributions.
  • How one can define a statistical error of a histogram?
  • What is the “central limit theorem”?
  • Test your EVO setup.

French literature books -good deal

Uncategorized

Payot (which is a stop away on the 16 tram on the way to Uni Mail or CERN) is having this deal of 4 folio books for 10 Francs. It’s an amazing deal, I already got 4 books. So if you want to read French, or if you are in love with Russian translated literature like I am, I think that you seriously need to check it out!
