-The following history plot from Giorgia shows a weird discrapancy in sigma. So, lower sigma corresponds to the fit with student-t + gaussian function and higher sigmas to double student-t function.{{:users:danyyl:dijet:screen_shot_2018-07-27_at_11.49.29.png?nolink}}

+I'm starting to investigate this and meanwhile improve my fitting strategy.
+I found out that the residual distribution has really weird shape. One can see on the following plot, that there is a triple-peak structure in the central region.{{ :users:danyyl:dijet:screen_shot_2018-07-27_at_12.09.45.png?nolink |}}
+After that I started to work on the fit function. Also, we asked Giorgia(Camilla, Stefanos and me) to check if she has the same structure.

+I was trying to find and fix the bug in the code corresponding generation step for the bias studies. I didn't find any software issue, so start to debug it (in a simple way with print outs after suspicious lines).
