◆ houghParamStrip()

double MuonR4::HoughHelpers::Phi::houghParamStrip	(	double	tanPhi,
		const MuonR4::HoughHitType &	dc
	)

straight line parametrisation for strip detector measurements, in the x-direction

Parameters

tanPhi	the input inclination angle
strip	the strip measurement (expressed as a space point)

Returns: the x offset needed to pass through the center of the strip space point for an inclination angle tanPhi

                                                                                         {
     return strip->positionInChamber().x() - tanPhi * strip->positionInChamber().z();
   }

◆ houghWidthStrip()

double MuonR4::HoughHelpers::Phi::houghWidthStrip	(	double	tanPhi,
		const MuonR4::HoughHitType &	dc,
		double	targetReso
	)

Uncertainty parametrisation for strip measurements.

Parameters

tanPhi	the input inclination angle (not used)
strip	the strip measurement (expressed as a space point)

Returns: the uncertainty on the x offset - based on the strip pitch
