Parameters:

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

  • absorption_bands (AbsorptionBands, optional) – Bands of absorption lines for line-by-line (LBL) calculations. See absorption_bands, defaults to self.absorption_bands [IN]

  • frequency_grid (AscendingGrid, optional) – A single frequency grid. See frequency_grid, defaults to self.frequency_grid [IN]

  • propagation_matrix_agenda (Agenda, optional) – Computes the propagation matrix, the non-LTE source vector, and their derivatives. See propagation_matrix_agenda, defaults to self.propagation_matrix_agenda [IN]

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

  • pol (Stokvec, optional) – The polarization selection vector (use the default unless you know what you are doing). Defaults to 1 0 0 0 [IN]

  • levels (ArrayOfQuantumLevelIdentifier) – The order of the energy levels. [IN]

  • convergence_limit (Numeric, optional) – Convergence criterion for the energy level distribution. Defaults to 1e-06 [IN]

  • consider_limb (Index, optional) – Whether to add extra limb points in zenith_gridProfilePseudo2D(). Defaults to 1 [IN]

  • collision_data (QuantumIdentifierGriddedField1Map) – Collision data for the transitions - for \(C_{ij}\) and \(C_{ji}\). [IN]

  • azimuth (Numeric, optional) – The azimuth of the radiation. Defaults to 0 [IN]

  • altitude_extrapolation (InterpolationExtrapolation, optional) – Extrapolation method along the altitude grid. Defaults to Linear [IN]
