Preparing the presentation for dijet group meeting. Link: https://indico.cern.ch/event/739327/contributions/3057480/attachments/1678163/2695094/dijet_presentation_29062018.pdf. To summarize:

1. allow third jet that is ISR jet (so event has 3 jets: 2 jets from the resonance and 3rd as ISR)
2. we sort them by pt (dijet system: 2 jets with the highest pt, 3rd with the highest pt is ISR)
3. trigger efficiency is 100% starting from 250 GeV
4. the best function for now: 6 parametric function form atlas/ua2 family
5. closure test shows that code works with my modifications and is set for dijet+ISR analysis
6. third jet shapes the data distribution (maybe we should put an upper cut on ISR jet pt)

Outlook: perform bias study for different functions, check if we can improve the fit yield using upper isr pt cut
