Parameters:

• ray_point (~pyarts3.arts.PropagationPathPoint, optional) – A single path point. Defaults to self.ray_point. [OUT]

• ray_path (~pyarts3.arts.ArrayOfPropagationPathPoint, optional) – A list path points making up a propagation path. Defaults to self.ray_path. [IN]

• atm_field (~pyarts3.arts.AtmField, optional) – An atmospheric field in ARTS, this is the main atmospheric data structure in ARTS. Defaults to self.atm_field. [IN]

• surf_field (~pyarts3.arts.SurfaceField, optional) – The surface field. Defaults to self.surf_field. [IN]

• max_stepsize (~pyarts3.arts.Numeric, optional) – A control parameter for stepping through layers in ray tracing. Defaults to self.max_stepsize. [IN]

• surf_search_accuracy (~pyarts3.arts.Numeric, optional) – The accuracy within which the surface intersection is counted as a hit. Defaults to 0.1 [IN]

• surf_safe_search (~pyarts3.arts.Index, optional) – Whether or not to search for the surface intersection in a safer but slower manner. Defaults to 1 [IN]
