When relating the more recent data for Monaco now available from SHOM to the earlier record a apparent anomaly was found in the documentation. In the historic hand written records the relationship between Zero NGF and Zero Hydrographique is quoted as being 0.490m. However on the recent datum diagram in site information document for Monaco also available from SHOM this relationship is quoted as being 0.400m. Both values were compared in the RLR adjustment. It was decided that the better agreement was the 0.400m adjustment giving a RLR adjustment figure of 6.504m.
