Fit sensitivities to study day to obtain initial values

The study campaign of 16.06.2021 is fitted to obtain the heuristic sensitivities. The fitting scheme adheres to the following order: 1.Obtain noise during pedestal run 2.Fit LER storage during LER beam decays 3.Fit LER inj during LER top ups 4.Fit HER storage during HER beam decays 5.Fit HER inj during HER top ups 6.FIt lumi while both rings carry current
