Member Function Documentation

◆ curvedToFlat()

static math_utils::Vector2D< float > o2::trk::SegmentationChip::curvedToFlat	(	const int	layer,
		const float	xCurved,
		const float	yCurved
	)

inlinestaticnoexcept

Transformation from the curved surface to a flat surface. Additionally a shift in the flat coordinates must be applied because the center of the TGeoShap when projected will be higher than the physical thickness of the chip. Thus we shift the projected center down by this difference to align the coordinate systems.

Parameters

layer	VD layer number
xCurved	Detector local curved coordinate x in cm with respect to the center of the sensitive volume.
yCurved	Detector local curved coordinate y in cm with respect to the center of the sensitive volume.

Returns: math_utils::Vector2D<float>: x and y represent the detector local flat coordinates x and y

this is equal to the circumference segment covered between y=0 and the phi angle

◆ detectorToLocal()

static constexpr bool o2::trk::SegmentationChip::detectorToLocal	(	int	iRow,
		int	iCol,
		float &	xRow,
		float &	zCol,
		int	subDetID,
		int	layer,
		int	disk
	)

inlinestaticconstexprnoexcept

Transformation from Detector cell coordinates to Geant detector centered local coordinates (cm)

Parameters

int	iRow Detector x cell coordinate.
int	iCol Detector z cell coordinate.
float	x Detector local coordinate x in cm with respect to the center of the sensitive volume.
float	z Detector local coordinate z in cm with respect to the center of the sensitive volume. If iRow and or iCol is outside of the segmentation range a value of -0.5Dx() or -0.5Dz() is returned.
int	subDetID Sub-detector ID (0 for VD, 1 for ML/OT)
int	layer Layer number (0 to 2 for VD, 0 to 7 for ML/OT)
int	disk Disk number (0 to 5 for VD)

		int	disk
	)

inlinestaticnoexcept

xRow = half chip width - iRow(center) * pitch zCol = iCol * pitch - half chip lenght

◆ flatToCurved()

static constexpr math_utils::Vector2D< float > o2::trk::SegmentationChip::flatToCurved	(	int	layer,
		float	xFlat,
		float	yFlat
	)

inlinestaticconstexprnoexcept

Transformation from the flat surface to a curved surface It works only if the detector is not rototraslated.

Parameters

layer	VD layer number
xFlat	Detector local flat coordinate x in cm with respect to the center of the sensitive volume.
yFlat	Detector local flat coordinate y in cm with respect to the center of the sensitive volume.

Returns: math_utils::Vector2D<float>: x and y represent the detector local curved coordinates x and y

		float	zCol,
		int &	iRow,

		int	subDetID,
		int	layer,
		int	disk
	)

inlinestaticnoexcept

Transformation from Geant detector centered local coordinates (cm) to Pixel cell numbers iRow and iCol. Returns kTRUE if point x,z is inside sensitive volume, kFALSE otherwise. A value of -1 for iRow or iCol indicates that this point is outside of the detector segmentation as defined.

Parameters

float	x Detector local coordinate x in cm with respect to the center of the sensitive volume.
float	z Detector local coordinate z in cm with respect to the center of the sensitive volulme.
int	iRow Detector x cell coordinate. Has the range 0 <= iRow < mNumberOfRows
int	iCol Detector z cell coordinate. Has the range 0 <= iCol < mNumberOfColumns
int	subDetID Sub-detector ID (0 for VD, 1 for ML/OT)
int	layer Layer number (0 to 2 for VD, 0 to 7 for ML/OT)
int	disk Disk number (0 to 5 for VD)
