GRS80 Moritz, H. (2000): Geodetic Reference System 1980. Parameter f, b see p. 131 WGS84 NGA (2014): World Geodetic System 1984, Its Definition and Relationships with Local Geodetic Systems. National Geospatial- Intelligence Agency (NGA) Standardization Document, Department of Defence, Office of Geomatics, Version 1.0.0, 2014-07-08. Parameter f see p. 3-3 Parameter b, e2, e2b see p. 3-9 Better use e2 and e2b from the NGA document, because it defines a and f and calculates b from it. But with the heavily rounded b value we would not calculate a correct f and all derived variables.
To make clear that they belong to the WGS84 values. Also insert e2 and e2b from Moritz (1980).
