Gets the previous refractive point along ray_path

This basically wraps ray_pointPastGeometric() but sets the zenith angle to the refracted zenith angle, i.e.,

\[\theta_{refracted} = \arcsin\left(\frac{n_{current}}{n_{next}}\sin(\theta_{current})\right)\]

Parameters:

  • ray_point (PropagationPathPoint, optional) – A single path point. See ray_point, defaults to self.ray_point [OUT]

  • ray_path (ArrayOfPropagationPathPoint, optional) – A list path points making up a propagation path. See ray_path, defaults to self.ray_path [IN]

  • atm_field (AtmField, optional) – An atmospheric field in ARTS. See atm_field, defaults to self.atm_field [IN]

  • surf_field (SurfaceField, optional) – The surface field. See surf_field, defaults to self.surf_field [IN]

  • max_stepsize (Numeric, optional) – A control parameter for stepping through layers in ray tracing. See max_stepsize, defaults to self.max_stepsize [IN]

  • single_dispersion (Numeric, optional) – A dispersion at a single freq point. See single_dispersion, defaults to self.single_dispersion [IN]

  • surf_search_accuracy (Numeric, optional) – The accuracy within which the surface intersection is counted as a hit. Defaults to 0.1 [IN]

  • surf_safe_search (Index, optional) – Whether or not to search for the surface intersection in a safer but slower manner. Defaults to 1 [IN]
