  * If the ensemble integration is completed, the following operations are required:
   * If more than one model task is used: Collect the sub-ensembles from all model tasks onto the processes that perform the analysis step. This operation is done by the subroutine `PDAF_gather_ens`.

   * Reset the control variables for the ensemble forecast (`initevol=1`, `member=1`, `step=step_obs+1`).
 
+In general, the put_state routines of all ensemble-based filters are quite general structures. For the implementation of a new filter one should be able to base on an existing routine, e.g. that of for the ETKF. Then, one has to adapt the interface for the required user-supplied routines of the new filter. In addition, the call of the routine `PDAF_X_update` holding the analysis step has to be revised (name of the routine, required user-supplied routines).
