bins

std::pair<std::size_t, std::size_t> Acts::SurfaceArrayNavigationPolicy::Config::bins

The number of bins in the local directions.

The interpretation depends on the layer type. A value of 0 in either direction requests automatic determination from the module layout (one bin per module), scaled by numberOfBinsFactor.

numberOfBinsFactor

double Acts::SurfaceArrayNavigationPolicy::Config::numberOfBinsFactor = 1.0

Multiplier applied to auto-determined (0) bin counts.

Values below one coarsen the grid, values above one refine it. Finer grids return fewer surfaces per neighbour query, cutting navigation candidate counts.
