+The page documents the user-supplied call-back routine `localize_covar_serial_pdaf`, which was introduced with PDAF V3.0.
 
 The routine `localize_covar_serial_pdaf` (`U_localize_covar_serial` inside PDAF) is a call-back routine that has to be provided by the user. 
-The routine is used in the ENSRF/EAKF and is called during the analysis step. The purpose of the routine is to apply covariance localization to the vectors '''Hi P''' and '''Hi PH^T^''' for the assimilation of a single observation (determined by the index `iobs` related to the observation operator '''Hi'''). Here '''Hi PH^T^''' is for the vector relating to the observed covariance matrix for the full observation vector, which is required for parallelization.
