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