Workspace.spectral_propmatInit(self, spectral_propmat: pyarts3.arts.PropmatVector | None = None, spectral_nlte_srcvec: pyarts3.arts.StokvecVector | None = None, spectral_propmat_jac: pyarts3.arts.PropmatMatrix | None = None, spectral_nlte_srcvec_jac: pyarts3.arts.StokvecMatrix | None = None, jac_targets: pyarts3.arts.JacobianTargets | None = None, freq_grid: pyarts3.arts.AscendingGrid | None = None) → None

Initialize spectral_propmat, spectral_nlte_srcvec, and their derivatives to zeroes.

This method must be used inside spectral_propmat_agenda and then be called first.

Parameters:

• spectral_propmat (PropmatVector, optional) – This contains the fully polarized propagation matrix for the current path point. See spectral_propmat, defaults to self.spectral_propmat [OUT]

• spectral_nlte_srcvec (StokvecVector, optional) – The part of the source vector that is due to non-LTE. See spectral_nlte_srcvec, defaults to self.spectral_nlte_srcvec [OUT]

• spectral_propmat_jac (PropmatMatrix, optional) – Partial derivative of the spectral_propmat with regards to jac_targets. See spectral_propmat_jac, defaults to self.spectral_propmat_jac [OUT]

• spectral_nlte_srcvec_jac (StokvecMatrix, optional) – Partial derivative of the spectral_nlte_srcvec with regards to jac_targets. See spectral_nlte_srcvec_jac, defaults to self.spectral_nlte_srcvec_jac [OUT]

• jac_targets (JacobianTargets, optional) – A list of targets for the Jacobian Matrix calculations. See jac_targets, defaults to self.jac_targets [IN]

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