Hi everyone,,

So, I am trying to do the trigger part. And the way I did is to select the useful elements in the leaves needed (e.g. from the leaf mu_py, I want a list of elements that satisfies the trigger threshold (?)) And the num_entries drop from 30839 to 2988… Attached is the 3 plots, the top one in the right is the raw mu_py, the top left one is selected mu_py…The bottom one is the fitted hinvm (hist of inv mass)…I don’t know if it makes sense… the top right one is kinda suspicious, especially everything is in one bin..(but maybe it was my code.) And I don’t think the bottom one is right either… I would expect a guassian curve (bec we are asked to fit with gaus and it would make sense to be a gaussian with a mean value of particle’s mass…) but i can’t tell where is wrong…
