Member Function Documentation

StatusCode lar_content::ThreeViewShowersAlgorithm::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

Definition at line 371 of file ThreeViewShowersAlgorithm.cc.

     if (((x - m_minX) < -std::numeric_limits<float>::epsilon()) || ((x - m_maxX) > +std::numeric_limits<float>::epsilon()))

     xBin = static_cast<int>(0.5f + m_nPoints * (x - m_minX) / (m_maxX - m_minX));
