Parameters:

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

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

  • freq_grid (AscendingGrid, optional) – A frequency grid. Unit: Hz. See freq_grid, defaults to self.freq_grid [IN]

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

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

  • key (AtmKey, optional) – Key to find the GeodeticField3 in the atmospheric field. Defaults to t [IN]

  • iteration_limit (Index, optional) – Maximum number of iterations. Defaults to 100 [IN]

  • dzen (Numeric, optional) – The zenith angle limit for the internal call to zen_gridProfilePseudo2D(). Defaults to 5 [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 zen_gridProfilePseudo2D(). Defaults to 1 [IN]

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

  • azi (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]
