    44 In PDAF3 it is possible to call any of the different ensemble filter methods using the single routine `PDAF3_assimilate` for online coupled assimilation, or `PDAF3_put_state` for offline (file-based) coupled programs. Also all 3D-Var methods can be called by `PDAF3_assimilate_3dvar_all` or `PDAF3_put_state_3dvar_all`.

     70=== Calling the analysis step in offline coupling with `assim_offline` ===
     71
     72For the offline coupled mode in PDAF2, one used `put_state` in combination with `PDAF_set_offline_mode`, which switched off the ensemble integration functionlity. In PDAF3, there are now `assim_offline` routines, e.g. `PDAF3_assim_offline`, which cab be directly called after the PDAF initialization. This simplifies the code for the offline mode.
