+Hints:
  * The routine is similar to `obs_op_pdaf` used for the global filters. However, with a domain-decomposed model `m_state_f` will contain parts of the state vector from neighboring model sub-domains. To make these parts accessible, some parallel communication will be necessary (The state information for a neighboring model sub-domain will be in the memory of the process that handles that sub-domain). The example implementation in `testsuite/dummymodel_1d` uses the function `MPI_AllGatherV` for this communication.
  * In case of a parallelized analysis step one has to take care that the order of observation in m_state_f is consistent with the order in the full observation vector `obs_f` generated by `init_obs_f_pdaf`.
