## * This is the run script to plot/fit RelIso using only MC events.
|
| 5 |
## * It calls fit_new.C and perform gaussian fit over all permutations of fit ranges,
|
| 6 |
## and make 2 version of plots: one zoomed-in on y-axis and the other not.
|
| 7 |
##
|
| 8 |
## * plot_qcd_estimate.C
|
| 9 |
##
|
| 10 |
## * It creates the following directories to store the output:
|
| 11 |
## mc_only_[DT]/nofit
|
| 12 |
## mc_only_[DT]/gaus_free12j_fix34j
|
| 13 |
## mc_only_[DT]/gaus_mean_0.3to0.6_12j_fix34j
|
| 14 |
## mc_only_[DT]/gaus_mean_0.4to0.6_12j_fix34j
|
| 15 |
## [DT] above means Date and Time, ie the time stamp of when the dir is created.
|
| 16 |
##
|
| 17 |
## * The time stamp format can be changed below by adapting the mytime variable.

# run_fit.cc calls fit_new.C, and runs the "fit" function for each fit range. For each case,
|
| 86 |
# it plots 6 histograms for alljet, 0 jet, 1 jet...4mjets.
|
| 87 |
# In doing so, it calculates estimates of the QCD in the signal region, and outputs the estimates
|
| 88 |
# to fit_res_gaus.txt, and the relative deviations ([est-true]/true) to est_free_gaus.txt.
|
| 89 |
# plot_qcd_estimate.C is then called, which reads in the values from est_free_gaus.txt, and plots these.
|
| 90 |
# It does this for unconstrained fits, or for constrained fits.
