Scales the neighborhood lookup depending on the inclination between propagation direction and surface normal.
This is a naive "first order" approximation where we assume the "uncertainty" is distance 1 in local grid units given perpendicular approach. This "uncertainty" is then scaled with$\frac{1}{\cos(\theta)}$ where $\theta$ is the enclosed angle between the grid surface and the track direction. An upper limit is deployed which also cuts off the generation of the next neighbor lookup table.
--- END COMMIT MESSAGE ---
An alternative formulation would be to assume a layer thickness and project it on the layer surface depending on the inclination.
One could go even further and make the lookup path dependent. But that clashes with our current assumption that the neighborhood is resolved once during initialization.
