Fitting the data

  1. Files were successfully created with one histogram (83.5e8 events for Run2016F). Data for Run F 2016
  2. Some of the files are empty. Need to understand why.
  3. Tried to fit first time: FAILED Fit first time the data
  4. Tried refit for 300-600 GeV dijet mass range. Have CALL LIMIT from Migrad
  5. Try to increase numbers of calls. Fit FAILS or CALL LIMIT 
    Fit:0: RuntimeWarning: Abnormal termination of minimization.

  6. Started to implement RooFit in my plot-fit code (from https://github.com/CMSDIJET/DijetRootTreeAnalyzer/blob/master/fit/fitMjj_scouting.py).
  7. Ran the jobs for another Runs of 2016.
What to do next?
  1. Add RooFit to my code
  2. Fit background with the help of RooFit
  3. Wait for whole data set
