    165164=== `U_prodRinvA_local` (prodrinva_local.F90) ===
    166165
     
    189188 * The observation vector `obs_l` is provided through the interface for cases where the observation error variance is relative to the actual value of the observations.
    190189
     190=== `U_init_n_domains` (init_n_domains.F90) ===
     191
     192This routine is used by all local filter algorithms (LSEIK, LETKF).
     193
     194The interface for this routine is:
     195{{{
     196SUBROUTINE init_n_domains(step, n_domains_p)
     197
     198  INTEGER, INTENT(in)  :: step        ! Current time step
     199  INTEGER, INTENT(out) :: n_domains_p ! number of analysis domains for local model sub-domain
     200}}}
     201
     202The routine is called during the analysis step before the loop over the local analysis domains is entered.
     203It has to provide the number of local analysis domains. In case of a domain-decomposed model the number of local analysis domain for the model sub-dmain of the calling process has to be initialized.
     204
     205Hints:
     206 * As a simple case, if the localization is only performed horizontally, the local analysis domain can be single vertical columns of the model grid. In this case `n_domains_p` is simply the number of vertical columns in the local model sub-domain.
