Calculates a geometrical propagation path step.
This function determines a propagation path step by pure geometrical calculations. That is, refraction is neglected. Path points are always included for crossings with the grids, tangent points and intersection points with the surface. The WSV
ppath_lmax
gives the option to include additional points to ensure that the distance along the path between the points does not exceed the selected maximum length. No additional points are included ifppath_lmax
is set to <= 0.For further information, type see the on-line information for
