propagation_matrix_agenda

Workspace.propagation_matrix_agenda: Agenda

Compute the propagation matrix, the non-LTE source vector, and their derivatives.

The intent of this agenda is to be the workhorse for the propagation matrix calculations that are happening deep in your ARTS method calls.

Tip

Use propagation_matrix_agendaAuto() after having defined your absorption data to create this agenda. It covers most use-cases.

It is possible to execute propagation_matrix_agenda directly from the workspace by calling propagation_matrix_agendaExecute().

As all agendas in ARTS, propagation_matrix_agenda is also customizable via its operator helper class: propagation_matrix_agendaOperator. See it, propagation_matrix_agendaSetOperator(), and propagation_matrix_agendaExecuteOperator() for more details.

propagation_matrix_agenda have these constraints ():

1. On output, propagation_matrix has the size of frequency_grid.

2. On output, propagation_matrix_source_vector_nonlte has the size of frequency_grid.

3. On output, propagation_matrix_jacobian has the shape of the target-count of jacobian_targets times the size of frequency_grid.

4. On output, propagation_matrix_source_vector_nonlte_jacobian has the shape of the target-count of jacobian_targets times the size of frequency_grid.
