    2020with the following arguments:
    21  * `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.
    22  * `U_distribute_state`:  The name of a user supplied routine that initializes the model fields from the array holding the ensemble of model state vectors.
    23  * `U_init_dim_obs_pdafomi`: The name of the user-supplied routine that initializes the observation information and provides the size of observation vector
    24  * `U_obs_op_pdafomi`: The name of the user-supplied routine that acts as the observation operator on some state vector
    25  * `U_prodRinvA_pdafomi`: The name of the user-supplied routine that computes the product of the inverse of the observation error covariance matrix with some matrix provided to the routine by PDAF.
    26  * `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.
    27  * `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.
    28  * `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.
    29  * `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.
    30  * `U_obs_op_lin_pdafomi`: The name of the user-supplied routine that acts as the linearized observation operator on some state vector
    31  * `U_obs_op_adj_pdafomi`: The name of the user-supplied routine that acts as the adjoint observation operator on some state vector
    32  * `U_init_n_domains`: The name of the routine that provides the number of local analysis domains
    33  * `U_init_dim_l`: The name of the routine that provides the state dimension for a local analysis domain
    34  * `U_init_dim_obs_l_pdafomi`: The name of the routine that initializes the size of the observation vector for a local analysis domain
    35  * `U_prodRinvA_l_pdafomi`: The name of the user-supplied routine that computes the product of the inverse of the observation error covariance matrix with some matrix provided to the routine by PDAF including localization.
    36  * `U_prepoststep`: The name of the pre/poststep routine as in `PDAF_get_state`
    37  * `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`.
    38  * `status`: The integer status flag. It is zero, if this routine is exited without errors.
     21with the following arguments:
     22 * `U_collect_state`: [[BR]]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.
