Datum, Ellipsoid, Delta a, Delta f (* 10^4), Delta X, Delta Y, Delta Z.

Delta parameters are with respect to WGS-84 parameters for conversion from the specified datum to WGS-84.

Parameter Delta a is the WGS-84 Equatorial radius minus the specified datum Equatorial radius in meters.

Parameter Delta f is the WGS-84 flattening minus the specified datum flattening multiplied by 10^4.

Delta X, Y, Z parameters are WGS-84 X, Y, Z parameters minus the specified datum X, Y, Z in meters.

The Delta X, Y, and Z parameters are added to the specified datum X, Y, Z to convert to WGS-84.

The source for most of these parameters is Defense Mapping Agency Technical Report, Department of Defense World Geodetic System 1984, DMA TR 8350.2 Second Edition, 1 September 1991.

WGS-84 Equatorial Radius (a) = 6378137.0
WGS-84 Flattening (f) = 1/298.257223563
