Detailed Description

A self-filling collection of 1-D histos with the same axis for efficiency calculation.

Like a SetOfHistograms, a SFEffSetOfHistograms contains a set of 1-dimensional TH1F histograms; these histograms are (normally) all created by the constructor. The histograms share the same axis binning, and their names and titles are created automatically.

Three histos are booked, one using BaseCut object cut1, one using cut2, the third will be an efficiency derived by dividing histo2 by histo1.

  • nx, ny are the number of histos in horizontal (nx) and vertical (ny) direction on a page
  • xmargin, ymargin are the corresponding values used by TPad::Divide.
  • color is passed to TPad::Divide.
  • log determines whether the histos shall be plotted logarithmically.
Parameters:
pad  usually a TCanvas object and MUST be provided
ps  usually a TPostscript object
option  an option string like "HE0"
across  arrange histos left-to-right (true) or top-to-bottom

void SFEffSetOfHistograms::Fill (   )  [virtual]
 

The Self-filler method.

Fill() evaluates the cut object to see whether an event fulfills the cut defined by the cut object, then evaluates the BinningFun object to see into which histogram to make an entry, then evaluates the xfun object to get the abscissa and the wfun object to obtain the weight. Optionally, the iter object serves as iterator.

Implements SFO.
