 +  - 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
