Using information from the NOAA website the RLR diagram has been revised. Previous Primary benchmark NO 1 1948 no longer appears in the NOAA reports. Primary benchmark is now 0000 S 1993 AS 29 ASPA 2002 2.557m above gauge datum.Documentation added 2013-02-28
Data for 2011 and 2012 almost look like a datum change but the profile must be real as that is how it appears on the NOAA website. It also buddy checks well with Apia B id. 1840Data Authority
