;  Changes:  added ellipsoid table
;
;September 26, 1998 - as released
;
;
;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.
;
;  The following table shows the radius, 1/f, delta a and delta 1/f for various ellipsoids
;
;   name                          a          1/f      WGS84a-a (da) ((WGS84f)-f)*1e4 (df)
