Member Data Documentation

maxRelativeDensityDev

double Acts::AdaptiveGridTrackDensity::Config::maxRelativeDensityDev = 0.01

The maximum relative density deviation from the main maximum to consider the second and third maximum for the highest-sum approach from above.

nSpatialTrkSigmas

double Acts::AdaptiveGridTrackDensity::Config::nSpatialTrkSigmas = 3.0

Number of standard deviations that the grid covers in z direction.

nTemporalTrkSigmas

double Acts::AdaptiveGridTrackDensity::Config::nTemporalTrkSigmas = 3.0

Number of standard deviations that the grid covers in t direction, not used if useTime == true.

spatialBinExtent

double Acts::AdaptiveGridTrackDensity::Config::spatialBinExtent = 15 * UnitConstants::um

Spatial extent of a bin in d0 and z0 direction, should always be set to a positive value.

spatialTrkGridSizeRange

GridSizeRange Acts::AdaptiveGridTrackDensity::Config::spatialTrkGridSizeRange = {std::nullopt, std::nullopt}

Optional minimal and maximal number of bins in z direction.

spatialWindow

std::pair<double, double> Acts::AdaptiveGridTrackDensity::Config::spatialWindow

Initial value:

= {-250 * UnitConstants::mm,
                                               250 * UnitConstants::mm}

Spatial window for filling the density map.

temporalBinExtent

double Acts::AdaptiveGridTrackDensity::Config::temporalBinExtent = 19 * UnitConstants::mm

Temporal extent of a bin, not used if useTime == true.

temporalTrkGridSizeRange

GridSizeRange Acts::AdaptiveGridTrackDensity::Config::temporalTrkGridSizeRange = {std::nullopt, std::nullopt}

Optional minimal and maximal number of bins in time direction.

temporalWindow

std::pair<double, double> Acts::AdaptiveGridTrackDensity::Config::temporalWindow

Initial value:

= {-10 * UnitConstants::ns,
                                                10 * UnitConstants::ns}

Temporal window for filling the density map.

useHighestSumZPosition

bool Acts::AdaptiveGridTrackDensity::Config::useHighestSumZPosition = false

Do NOT use just the z-bin with the highest track density, but instead check (up to) first three density maxima (only those that have a maximum relative deviation of 'relativeDensityDev' from the main maximum) and take the z-bin of the maximum with the highest surrounding density sum.

useTime

bool Acts::AdaptiveGridTrackDensity::Config::useTime = false

Flag indicating whether to use time information in track density calculation.
