Detailed Description

Class to store a single weight entry (one bin).

Stores a single binned weight, corresponding to a pair of bins from the underlying numerator and denominator histograms. Allows access to quantities like central values, uncertainties and PDFs.

Constructor & Destructor Documentation

APWeightEntry::APWeightEntry (  ) 

Default constructor.

APWeightEntry::APWeightEntry ( unsigned int  val_denominator,
unsigned int  val_numerator,
double  scale,
bool  isTrig = false 
)

Constructor, takes n_denom, n_num, the relative scale of the used samples or an additional user scale and a bool if the entry is a trigger weight.

APWeightEntry::~APWeightEntry (  )  [virtual]

Default destructor.


Member Function Documentation

vector< int > APWeightEntry::GetCoords (  )  const

Returns the coordinates of the current entry in the original histogram.

double APWeightEntry::GetExpectancy (  )  const

Get Expectancy value of efficiency/weight.

unsigned int APWeightEntry::GetID (  )  const

Returns the internal ID (used by APReweight/APReweight2D/APReweight3D/APReweightND).

vector< int > APWeightEntry::GetOriginalDimensions (  )  const

Returns the dimensions and amounts of bins for each dimension of the original histogram.

TH1F * APWeightEntry::GetPDF (  ) 

Returns the calculated PDF.

double APWeightEntry::GetRandom (  ) 

Get random number from PDF.

double APWeightEntry::GetStatUncertHigh (  )  const

Get upper bound of asymmetric statistical uncertainty.

double APWeightEntry::GetStatUncertLow (  )  const

Get lower bound of asymmetric statistical uncertainty.

double APWeightEntry::GetSysUncert (  )  const

Get absolute systematic uncertainty value of efficiency/weight.

double APWeightEntry::GetSysUncert2 (  )  const

bool APWeightEntry::IsNaN (  )  const

Returns true if instance is NaN.

bool APWeightEntry::IsTrig (  )  const

Returns true if instance is trigger based.

void APWeightEntry::ReadEfficiency ( double  efficiency,
double  err_low,
