GaussianGridTrackDensity
¶ Implements a 1-dim density grid to be filled with track Gaussian distributions.
Each single track is modelled as a 2(!)-dim Gaussian distribution grid in the d0-z0 plane, but only the overlap with the z-axis (i.e. a 1-dim density vector) needs to be calculated. The position of the highest track density (of either a single bin or the sum of a certain region) can be determined. Single tracks can be cached and removed from the overall density.
- Template Parameters
mainGridSize
: The size of the z-axis 1-dim main density gridtrkGridSize
: The 2(!)-dim grid size of a single track, i.e. a single track is modelled as a (trkGridSize x trkGridSize) grid in the d0-z0 plane. Note: trkGridSize has to be an odd value.

(float zMinMax_ = 100)¶ - Parameters
zMinMax
: The minimum and maximum z-values (in mm) that should be covered by the main 1-dim density grid along the z-axis Note: This value together with ‘mainGridSize’ determines the overall bin size to be used as seen below
