Detailed Description

template<detail::TrackParamsGrid grid_t>
class Acts::TrackParamsLookupAccumulator< grid_t >

Class to accumulate and average track lookup tables.

Template Parameters

Grid	type for track parameters accumulation

This class is used to accumulate track parameters in reference layer grids and average them to create a lookup table for track parameter estimation in seeding

Note

Geometry context is left to be handled by the user outside of accumulation
