Add
L1_HTT240
to the selection that I am using to the analysisClass.cc and to my fit-plot script. Check locally if it works. Made plot with
L1_HTT240 == 1
from histogram and from tree using the selection. On ratio plot draw only the histogram within fit range. Fit looks nice, but the Hesse matrix is not positive defined (
FROM HESSE STATUS=NOT POSDEF
). Can be caused by correlation between the parameters in the background fit function (chisquare/ndof = 0.498048183018 also can be caused by correletion, ndof = Nbins - 4).
