// * Perform fit to RelIso distribution to estimate QCD in various jet bins.
|
| 5 |
|
|
// * Different fitting procedures are employed:
|
| 6 |
|
|
// (a) free functional fits in all jet bins
|
| 7 |
|
|
// (b) free fit in 1,2j, but constrained fits in 3,4mj, using
|
| 8 |
|
|
// fitted results from 1,2j.
|
| 9 |
|
|
// (c) plot RelIso without fitting.
|
| 10 |
|
|
//
|
| 11 |
|
|
// * Configurable options:
|
| 12 |
|
|
// (a) fit function: pol3, gaus
|
| 13 |
|
|
// (b) fit range
|
| 14 |
|
|
// (c) whether to zoom in on y-axis or not
|
| 15 |
|
|
//
|
| 16 |
|
|
// * Each fit produces one such multi-pad plot:

|
|
// Tips/reminder:
|
| 26 |
|
|
// - To use only MC, use run_mc.sh
|
| 27 |
|
|
// - To fit data, use run_data.sh
|
| 28 |
|
|
// - Every time new data is used, the integrated luminosity needs to be updated (intlumi).
|
| 29 |
|
|
//
|
| 30 |
|
|
// Things to look out for:
|
| 31 |
|
|
// - Because data is plotted first, sometimes the MC histograms are
|
| 32 |
|
|
// cut off in the y-scale. To cure this, set explicitly the upper limit on y
|
| 33 |
|
|
// using the YMAX_nj (n=all,1,2 etc) global variables.
|
| 34 |
|
|
//
|
| 35 |
|
|
// If code crashes, turn on the (global) 'debug' flag and re-run, but hopefully you won't need this!
