class AtlPdfReweightingTool: public AtlAnalysisTool


 Wrapper for Soeren's Pdf reweighting class
 needed for the evaluation of Pdf systematics

 Simply create the tool in your task (see AtlAppAnalysisTask) or
 your analysis selector (AtlSelector). Choose the systematics mode
 (up/down/nominal) by setting the public data member fSystMode (eg
 by using AtlAppAnalysisTask::SetToolVariable()).

 Next add the histograms of the observable you want to reweight by
 using AddObservable(). Here you have to give the full path name to
 of each histogram inside the output file. Note that currently
 1-dim. and 2-dim. histograms are supported. Hint: in case of event
 counting use a single-bin histogram. AddObservable() can be called
 anytime before the event loop, for instance in BookHistograms().

Function documentation

AtlPdfReweightingTool(const char* name, const char* title)

 Default constructor

~AtlPdfReweightingTool()

 Default destrcuctor

void BookHistograms()

 Book observables

Bool_t AnalyzeEvent()

 Compute Pdf weights

void Print() const

 Prints chosen parameter settings for the tool to
 standard output

void SetBranchStatus()

 Enable on needed branches

void Init()

 Init Pdf tool

void AddObservable(const char* HistName)

 Add observable to reweight.

 The given histogram is the histogram inside the user analysis
 used to histogram the observable in question. The full path
 name of the histogram inside the output file is needed here.

 In case of event counting use a single-bin histogram.

void FillObservables()

 Fill observables

void Terminate()

 Terminate routine called by AtlSelector::SlaveTerminate().

 Here, the final Pdf uncertainty is determined. The original
 histograms for each given observable are replaced with the
 respected up/down variations.

void FirstEvent()

 Initialize normalization scale factors and
 add observables to the Pdf tool

void AddObs1D(TH1F* h_orig)

 Add 1-dim. histogram to the list of observables of the Pdf tool

void AddObs2D(TH2F* h_orig)

 Add 2-dim. histogram to the list of observables of the Pdf tool

 Internally the 2-dim. histogram is splitted into 1-dim.
 histograms for each bin along the y-axis.

TList* FIndObjects(TList* list, const TRegexp& pat)

 Find all objects inside the given list whose names fulfill the
 regular expression.


 !!! The user is responsible for deleting the returned list !!!
