A value of MTL-MSL=-39 mm has been derived using a historic databank of harmonic tidal constants gathered by the International Hydrographic Organization (IHO). Care must be taken when using these IHO constants, though, as there are many known errors in tidal amplitudes and phases. As the correction is only applied to RLR data and the data from 1956 is metric, it is not used in the data set. Should this period become metric in future, however, it would be used.
