| 20 | | * `U_collect_state`: The name of the user-supplied routine that initializes a state vector from the array holding the ensemble of model states from the model fields. This is basically the inverse operation to `U_distribute_state` used in `PDAF_get_state` as well as here. |
| 21 | | * `U_distribute_state`: |
| 22 | | * `U_init_dim_obs_pdafomi`: The name of the user-supplied routine that initializes the observation information and provides the size of observation vector |
| 23 | | * `U_cvt_ens`: The name of the user-supplied routine that applies the ensemble control-vector transformation (square-root of the B-matrix) on some control vector to obtain a state vector. |
| 24 | | * `U_cvt_adj_ens`: The name of the user-supplied routine that applies the adjoint ensemble control-vector transformation (with square-root of the B-matrix) on some state vector to obtain the control vector. |
| 25 | | * `U_cvt`: The name of the user-supplied routine that applies the control-vector transformation (square-root of the B-matrix) on some control vector to obtain a state vector. |
| 26 | | * `U_cvt_adj`: The name of the user-supplied routine that applies the adjoint control-vector transformation (with square-root of the B-matrix) on some state vector to obtain the control vector. |
| 27 | | * `U_obs_op_pdafomi`: The name of the user-supplied routine that acts as the observation operator on some state vector |

| 29 | | * `U_obs_op_lin_pdafomi`: The name of the user-supplied routine that acts as the adjoint observation operator on some state vector |
| 30 | | * `U_prepoststep`: The name of the pre/poststep routine as in `PDAF_get_state` |
| 31 | | * `U_next_observation`: The name of a user supplied routine that initializes the variables `nsteps`, `timenow`, and `doexit`. The same routine is also used in `PDAF_get_state`. |
| 32 | | * `status`: The integer status flag. It is zero, if the routine is exited without errors. It is recommended that the value of `status_pdaf` is checked in the program after the routine is executed. Only if its value is 0 the initialization was successful. |
