The fit with 5 parameter atlas function: fit_mjj_full_calotrijet2016_1.pdf. Chi square is too large and fit is not good.

We need to prepare the bias studies to understand which function to choose in our analysis.

Tried to use the “new” function from dijet group: fit_mjj_full_calotrijet2016_2.pdf. This function is better in sense of chi square, but still not good (6 parameters).

So, the previous results from yesterday were proved.

Find the best fit function to fit the background

Perform the bias study for the best function; but before that - set the combine tool in dijet group framework to use in dijet + isr analysis.
