It has come to our notice that there was an error in the RLR diagram for Ponta Delgada. The diagram has been re-calculated, as a result the RLR factor changed from 5.887m to 5.874m. The data has been adjusted.

A value of MTL-MSL=3 mm has been derived using the GESLA2 (high-frequency tide gauge) dataset using harmonic constituents. As the correction is only applied to RLR data and the data from 1924-1977 is metric, it is not used in the data set. Should this period become RLR in future it would be used.
