Constructor & Destructor Documentation

◆ TRestComponent() [1/2]

TRestComponent::TRestComponent	(	const char *	cfgFileName,

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters

It returns the intensity/rate (in seconds) corresponding to the generated distribution or formula evaluated at the position of the parameter space given by point.

The response matrix (if defined) will be used to convolute the expected rate. The TRestResponse metadata class defines the variable where the response will be applied.

Definition at line 168 of file TRestComponent.cxx.

◆ GetRawRate()

Double_t TRestComponent::GetRawRate ( std::vector< Double_t > point )

It returns the intensity/rate (in seconds) corresponding to the generated distribution or formula evaluated at the position of the parameter space given by point. The returned rate is integrated to the granularity of the parameter space (cell size). To get a normalized rate use TRestComponent::GetNormalizedRate.

The size of the point vector must have the same dimension as the dimensions of the distribution.

If interpolation is enabled (which is disabled by default) the rate will be evaluated using interpolation with neighbour histogram cells.
