 For the documentation of the calling interface of `PDAF_eofcovar` see [wiki:PDAF_eofcovar the detail page about the routine].

+
+For step 3, the routine [wiki:PDAF_sampleens PDAF_sampleens] performs the second-order exact sampling. For this task, one provides the routine the singular vectors and values from step 2 and a central state for the ensemble mean. The routine will then generate and return the ensemble to the program that called `PDAF_sampleens`. 
+
+The ensemble generation is usually done when a data assimilation sequence is initialized. One read the singular vectors and values from the file generate in step 2. In addition one read the central state of the ensemble. then one calls `PDAF_sampleens`  and obtains an ensmeble for the data assimilation.
