text: The parameters determined are usually the semi-major axis, a {\displaystyle a} , and either the semi-minor axis, b {\displaystyle b} , or the inverse flattening 1 / f {\displaystyle 1/f} , (where the flattening is f = ( a − b )
text: The ellipsoid is completely parameterised by the semi-major axis a {\displaystyle a} and the flattening f {\displaystyle f} .
