Fitting the data
Files were successfully created with one histogram (83.5e8 events for Run2016F).

Some of the files are empty. Need to understand why.
Tried to fit first time: FAILED

Tried refit for 300-600 GeV dijet mass range. Have CALL LIMIT from Migrad

Try to increase numbers of calls. Fit FAILS or CALL LIMIT
Fit:0: RuntimeWarning: Abnormal termination of minimization.

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
