Member Function Documentation

StatusCode lar_content::ThreeDShowersAlgorithm::XSampling::GetBin	(	const float	x,
		int &	xBin
	)		const

Convert an x position into a sampling bin.

Parameters

x	the input x coordinate
xBin	to receive the x bin

Returns

status code, faster than throwing in regular use-cases
