ray_path_observer_agenda
========================

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.ray_path_observer_agenda
   :type: ~pyarts3.arts.Agenda
   
   Get the propagation path as it is obeserved.
   
   The intent of this agenda is to provide a propagation path as seen from the observer
   position and line of sight.
   
   .. tip::
       The perhaps easiest way to set this agenda up is to use the :func:`~pyarts3.workspace.Workspace.ray_path_observer_agendaSetGeometric` method.
   
   It is possible to execute :attr:`~pyarts3.workspace.Workspace.ray_path_observer_agenda` directly from the workspace by calling :func:`~pyarts3.workspace.Workspace.ray_path_observer_agendaExecute`.
   
   As all agendas in ARTS, :attr:`~pyarts3.workspace.Workspace.ray_path_observer_agenda` is also customizable via its operator helper class: :class:`~pyarts3.arts.ray_path_observer_agendaOperator`.
   See it, :func:`~pyarts3.workspace.Workspace.ray_path_observer_agendaSetOperator`, and :func:`~pyarts3.workspace.Workspace.ray_path_observer_agendaExecuteOperator` for more details.
   
   
   
   
   Parameters
   ----------
   ray_path : ~pyarts3.arts.ArrayOfPropagationPathPoint

   spectral_radiance_observer_position : ~pyarts3.arts.Vector3
       The position of an observer of spectral radiance. See :attr:`~pyarts3.workspace.Workspace.spectral_radiance_observer_position` **[IN]**
   spectral_radiance_observer_line_of_sight : ~pyarts3.arts.Vector2
       The line-of-sight of the observer of spectral radiance. See :attr:`~pyarts3.workspace.Workspace.spectral_radiance_observer_line_of_sight` **[IN]**
