Following the 2016 levelling exercise some adjustments have been made to the benchmark reference heights - at Helsinki this was +1mm for BM 7HB. The adjustments are a result of more accurate measuring and calculations using the N2000 height system. The RLR diagram has been re-drawn because of this.
