Constructor & Destructor Documentation

GResponse::edisp_kern::edisp_kern	(	const GResponse *	parent,
		const GObservation *	obs,
		const GModelSky *	model,
		const GEvent *	event,
		const GTime &	srcTime,
		const bool &	grad
	)

Constructor for energy dispersion integration kernel class.

Parameters

[in]	parent	Pointer to response.
[in]	obs	Pointer to observation.
[in]	model	Pointer to sky model.
[in]	event	Pointer to event.
[in]	srcTime	True time.

Member Function Documentation

const GNdarray & GResponse::edisp_kern::array ( void  ) const

virtual

Return energy dispersion integration kernel.

Returns

Ndarray.

This method returns an Ndarray with the last values that were computed by the eval() method. In case that eval() was not called before, the method returns an Ndarray with the right dimension and with all values set to zero.

Implements GFunctions.

Definition at line 1190 of file GResponse.cpp.

GNdarray GResponse::edisp_kern::eval ( const double &  etrue )

virtual

Evaluate energy dispersion integration kernel.

Parameters

[in]

etrue

True photon energy in MeV.

This method implements the integration kernel needed for the GResponse::edisp_kern() class.

Implements GFunctions.
