Some parameters are only used by the user-supplied call back routines. Such options are, for example, `locweight` and `cradius` that specify the localization. These options can be found in the tutorial implementation in ` /tutorial/online_2D_serialmodel`.42 The available configuration options of the filters are provided on the [wiki:AvailableOptionsforInitPDAF overview page on filter-specific options].
