User-supplied routine for PDAF. ! Used in the filters: LSEIK/LETKF/LESTKF ! ! The routine is called in PDAF\_X\_update ! at the beginning of the analysis step before ! the loop through all local analysis domains. ! It has to set the number of local analysis ! domains for the PE-local domain. ! ! !REVISION HISTORY: ! 2013-02 - Lars Nerger - Initial code !
