spectral_propmatInit

Workspace.spectral_propmatInit(self, spectral_propmat: PropmatVector = self.spectral_propmat, spectral_nlte_srcvec: StokvecVector = self.spectral_nlte_srcvec, spectral_propmat_jac: PropmatMatrix = self.spectral_propmat_jac, spectral_nlte_srcvec_jac: StokvecMatrix = self.spectral_nlte_srcvec_jac, jac_targets: JacobianTargets = self.jac_targets, freq_grid: AscendingGrid = self.freq_grid) → 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 (~pyarts3.arts.PropmatVector, optional) – This contains the fully polarized propagation matrix for the current path point. Defaults to self.spectral_propmat. [OUT]

  • spectral_nlte_srcvec (~pyarts3.arts.StokvecVector, optional) – The part of the source vector that is due to non-LTE. Defaults to self.spectral_nlte_srcvec. [OUT]

  • spectral_propmat_jac (~pyarts3.arts.PropmatMatrix, optional) – Partial derivative of the spectral_propmat with regards to jac_targets. Defaults to self.spectral_propmat_jac. [OUT]

  • spectral_nlte_srcvec_jac (~pyarts3.arts.StokvecMatrix, optional) – Partial derivative of the spectral_nlte_srcvec with regards to jac_targets. Defaults to self.spectral_nlte_srcvec_jac. [OUT]

  • jac_targets (~pyarts3.arts.JacobianTargets, optional) – A list of targets for the Jacobian Matrix calculations. Defaults to self.jac_targets. [IN]

  • freq_grid (~pyarts3.arts.AscendingGrid, optional) – A frequency grid. Unit: Hz. Defaults to self.freq_grid. [IN]
