   * 4: ETKF

- * `subtype`: An integer defining the sub-type of the filter algorithm (see the example code in `testsuite/src/dummymodel_1D` for choices)

+ * `subtype`: An integer defining the sub-type of the filter algorithm (see the example code in `templates/online_omi/init_pdaf.F90` for choices). 
+  * If `PDAF_init` is called with `subtype=-1` the available options are shown for the selected filter algorithm.
  * `step_null`: An integer defining the initial time step. For some cases it can use useful to set `step_null` larger to 0. 
- * `filter_param_i`: Integer array collecting several variables for PDAF. The first two variables are mandatory and equal for all filters. Further variables are optional (see example code). The mandatory variables are in the following order:
+ * `filter_param_i`: Integer array collecting several variables for PDAF. The first two variables are mandatory and equal for all filters. Further variables are optional (see example code or use `subtype=-1` to display available options.). The mandatory variables are in the following order:
   * The size of the local state vector for the current process.
   * The ensemble size for all ensemble-based filters (or the rank of the state covariance matrix for mode-based filters like SEEK)
  * `length_filter_param_i`: An Integer defining the length of the array `filter_param_i`. The entries in the array are parsed up to this index.
- * `filter_param_r`: Array of reals collecting floating point variables for PDAF. The first variable is mandatory and equal for all filters.  Further variables are optional (see example code in `testsuite/src/dummymodel_1D`). The mandatory variable is:
-  * The value of the forgetting factor (required to be larger than zero)
+ * `filter_param_r`: Array of reals collecting floating point variables for PDAF. The first variable is mandatory and equal for all filters.  Further variables are optional (see example code in `templates/online_omi/init_pdaf.F90` or use `subtype=-1` to display available options.). The mandatory variable is:
+  * The value of the forgetting factor controlling covariance inflation (required to be larger than zero; common are values between 0.9 and 1.0. For 1.0 the ensemble is not inflated.)
  * `length_filter_param_r`: An Integer defining the length of the array `filter_param_r`. The entries in the array are parsed up to this index.
- * `COMM_model`: The communicator variable `COMM_model` as initialized by `init_parallel_pdaf`. If the model-communicator is named differently in the actual program, the name has to be adapted
- * `COMM_filter`: The communicator variable `COMM_filter` as initialized by `init_parallel_pdaf`.
- * `COMM_couple`: The communicator variable `COMM_couple` as initialized by `init_parallel_pdaf`.
- * `task_id`: The index of the model tasks  as initialized by `init_parallel_pdaf`.
- * `n_modeltasks`: The number of model tasks as defined before the call to `init_parallel_pdaf`.
- * `filterpe`: The flag showing if a process belongs to `COMM_filter` as initialized by `init_parallel_pdaf`.
+ * `COMM_model`: The communicator variable `COMM_model` as initialized by `init_parallel_pdaf`. (Usually stored in the module `mod_assimilation`)

+ * `n_modeltasks`: The number of model tasks as defined before the call to `init_parallel_pdaf`. (Usually stored in the module `mod_assimilation`)
+ * `filterpe`: A logical flag showing whether a process belongs to `COMM_filter` as initialized by `init_parallel_pdaf`. (Usually stored in the module `mod_assimilation`)
  * `screen`: An integer defining whether information output is written to the screen (i.e. standard output). The following choices are available:
-  * 0: quite mode - no information is displayed. 
+  * 0: quiet mode - no information is displayed. 
   * 1: Display standard information (recommended)
   * 2: as 1 plus display of timing information during the assimilation process
-  * 3: Display detailed information for debugging
- * `status_pdaf`: An integer used as status flag of PDAF. If `status_pdaf` is zero upon exit from `PDAF_init` the initialization was successful. An error occurred for non-zero values. (The error codes are documented in the routine PDAF_init.) 
+ * `status_pdaf`: An integer used as status flag of PDAF. If `status_pdaf` is zero upon exit from `PDAF_init` the initialization was successful. An error occurred for non-zero values. (The error codes are documented in the routine `PDAF_init`.) 
 
 It is recommended that the value of `status_pdaf` is checked in the program after PDAF_init is executed. Only if its value is 0 the initialization was successful.
