Kaon_LT Experiment

Made a code which checking aerogel gain stability. The code calculate single photoelectron peak mean value for each channel using Gaussian function and put results in a Ttree. Also wrote small script which access result.root file and plot final graph. The example of stability plot is attached. Code optimization still needed and I am playing around fit method because it affecting the result and interpretation of it. If taking into account that we have 1.5 photoelectron cut on aerogel we in a good shape in terms of stability.
