A search was made on the Norwegian website to see if the datum issue could be resolved. From looking at the datasets it became obvious that they had been totally revised. Datum figures were found on the web and applied to the data. RLR was recalculated for 2008. There is still a query on the very early data which still needs confirming with the authority.
