bFieldInZ

float Acts::CylindricalSpacePointGrid2::Config::bFieldInZ = 0 * UnitConstants::T

magnetic field

bottomBinFinder

std::optional<GridBinFinder<3ul> > Acts::CylindricalSpacePointGrid2::Config::bottomBinFinder

cotThetaMax

float Acts::CylindricalSpacePointGrid2::Config::cotThetaMax = 10.01788

maximum forward direction expressed as cot(theta)

deltaRMax

float Acts::CylindricalSpacePointGrid2::Config::deltaRMax = 270 * UnitConstants::mm

maximum distance in r from middle space point to bottom or top spacepoint

impactMax

float Acts::CylindricalSpacePointGrid2::Config::impactMax = 0 * UnitConstants::mm

maximum impact parameter in mm

maxPhiBins

int Acts::CylindricalSpacePointGrid2::Config::maxPhiBins = 10000

maximum number of phi bins

minPt

float Acts::CylindricalSpacePointGrid2::Config::minPt = 0 * UnitConstants::MeV

minimum pT

navigation

std::array<std::vector<std::size_t>, 3ul> Acts::CylindricalSpacePointGrid2::Config::navigation

phiBinDeflectionCoverage

int Acts::CylindricalSpacePointGrid2::Config::phiBinDeflectionCoverage = 1

Multiplicator for the number of phi-bins.

The minimum number of phi-bins depends on min_pt, magnetic field: 2*pi/(minPT particle phi-deflection). phiBinDeflectionCoverage is a multiplier for this number. If numPhiNeighbors (in the configuration of the BinFinders) is configured to return 1 neighbor on either side of the current phi-bin (and you want to cover the full phi-range of minPT), leave this at 1.

phiMax

float Acts::CylindricalSpacePointGrid2::Config::phiMax = std::numbers::pi_v<float>

maximum phi value for phiAxis construction

phiMin

float Acts::CylindricalSpacePointGrid2::Config::phiMin = -std::numbers::pi_v<float>

minimum phi value for phiAxis construction

rBinEdges

std::vector<float> Acts::CylindricalSpacePointGrid2::Config::rBinEdges {}

rMax

float Acts::CylindricalSpacePointGrid2::Config::rMax = 600 * UnitConstants::mm

maximum extension of sensitive detector layer relevant for seeding as distance from x=y=0 (i.e.

in r)

rMin

float Acts::CylindricalSpacePointGrid2::Config::rMin = 0 * UnitConstants::mm

minimum extension of sensitive detector layer relevant for seeding as distance from x=y=0 (i.e.

in r) WARNING: if rMin is smaller than impactMax, the bin size will be 2*pi, which will make seeding very slow!

topBinFinder

std::optional<GridBinFinder<3ul> > Acts::CylindricalSpacePointGrid2::Config::topBinFinder

zBinEdges

std::vector<float> Acts::CylindricalSpacePointGrid2::Config::zBinEdges {}

enable non equidistant binning in z

zMax

float Acts::CylindricalSpacePointGrid2::Config::zMax = 2800 * UnitConstants::mm

maximum extension of sensitive detector layer relevant for seeding in positive direction in z

zMin

float Acts::CylindricalSpacePointGrid2::Config::zMin = -2800 * UnitConstants::mm

minimum extension of sensitive detector layer relevant for seeding in negative direction in z
