HGCPlotting

Plotting scripts for HGCal

Setting up

To compile: type make To run ./FillHistograms --in_directory inputdirectory --out_directory outputdirectory --max_events 10000

inputdirectory can be local or remote (searches for ntuple_i.root, where i is a number). --max_events is an optional variable

Creating your own histograms

The code works by defining 'Histogram sets' - i.e. a set of histograms for a given study. The histogram sets you choose are currently chosen in the Constructor function at the top of src/HGCPlotting.cxx

Define a new histogram set in the LoadHistoTemplates function in src/Histogramming.cxx. The histograms are filled in the FillAllHists function. The histograms can be filled directly with variables from the input tree, or with custom variables defined in the function CalculateTriggerCellVariables and saved into the _event_variables map. More functions can be added for specific calculations.

Important notes

• The branches/leaves of the input ntuple you want to analyse are turned on or off using SetBranchStatus in src/HGCPlotting.cxx. A minimal number are turned on by default for speed purposes.
