Agenda Spectral radiance as seen from the input position and environment

The intent of this agenda is to provide a spectral radiance as seen from the observer position and line of sight.

It also outputs the ray_path as seen from the observer position and line of sight. This is useful in-case a call to the destructive spectral_radianceApplyUnitFromSpectralRadiance() is warranted

The output must be sized as:

• spectral_radiance : (frequency_grid)

• spectral_radiance_jacobian : (jacobian_targets, frequency_grid)

• ray_path : (Unknown)

Parameters:

• spectral_radiance (StokvecVector) – A spectral radiance vector. See :attr: ~pyarts.workspace.Workspace.spectral_radiance [OUT]

• spectral_radiance_jacobian (StokvecMatrix) – Jacobian of spectral_radiance with respect to jacobian_targets. See :attr: ~pyarts.workspace.Workspace.spectral_radiance_jacobian [OUT]

• ray_path (ArrayOfPropagationPathPoint) – A list path points making up a propagation path. See :attr: ~pyarts.workspace.Workspace.ray_path [OUT]

• frequency_grid (AscendingGrid) – A single path point’s frequency grid. See :attr: ~pyarts.workspace.Workspace.frequency_grid [IN]

• jacobian_targets (JacobianTargets) – A list of targets for the Jacobian Matrix calculations. See :attr: ~pyarts.workspace.Workspace.jacobian_targets [IN]

• spectral_radiance_observer_position (Vector3) – The position of an observer of spectral radiance. See :attr: ~pyarts.workspace.Workspace.spectral_radiance_observer_position [IN]

• spectral_radiance_observer_line_of_sight (Vector2) – The position of the observer of spectral radiance. See :attr: ~pyarts.workspace.Workspace.spectral_radiance_observer_line_of_sight [IN]

• atmospheric_field (AtmField) – An atmospheric field in ARTS. See :attr: ~pyarts.workspace.Workspace.atmospheric_field [IN]

• surface_field (SurfaceField) – The surface field describes the surface properties. See :attr: ~pyarts.workspace.Workspace.surface_field [IN]
