Detailed Description

TimePix pixel chip.

Constructor & Destructor Documentation

marlintpc::tp_PixelChip::tp_PixelChip	(	const int	chipId,
		pixelListType &	pixelList,
		const int	mpSize,
		const double	sigmaZ
	)

Construct TimePix (macro) pixel bin.

Parameters

[in]	chipId	chipID
[in]	pixelList	list of pixels
[in]	mpSize	macro pixel size
[in]	sigmaZ	resolution in Z

Member Function Documentation

int marlintpc::tp_PixelChip::findSegments	(	const double	bfac,
		const int *	iCuts,
		const double *	dCuts
	)

Find segments.

Use pairs of macro pixels as seed for road search (in XY, SZ), take road with minimal Chi2

Parameters

[in]	bfac	Bz*c
[in]	iCuts	(int) cuts for segment finding : (maxMult, minPixels, minDist)
[in]	dCuts	(double) cuts for segment finding : (maxResXY, maxResZ, maxChi2, maxSvar, maxGap)

Returns

number of segments found

• maxMult: max. number of macro pixels in bin for seeds
• minPixels: min. number of pixels for seeding macro pixel
• minDist: min. distance of seeding pair in XY (in macro pixels)
• maxResXY: max. XY residuum (distance perpendicular to seed (line), ~ macro pixel size)
• maxResZ: max. Z residuum
• maxChi2: max Chi2 from residuals and spread inside macro pixels
• maxSvar: max. (rel.) variance in S of macro pixels (sparse track: up to 0.25, uniform: 1./12.)
• maxGap: max. gap (in arclength)
