flattening

f

ratio of the difference between the semi-major axis (a) and semi-minor axis (b) of an ellipsoid to the semi-major axis; f = (a – b)/a

Note to entry: Sometimes inverse flattening 1 / f = a / ( a b ) is given instead; 1 / f is also known as reciprocal flattening.

achatamiento

f

razón de la diferencia entre el semieje mayor (a) y el semieje menor (b) de un elipsoide con el semieje mayor; f = (a - b) / a

Nota: a veces en su lugar se da la inversa del achatamiento 1/f = a/(a-b); 1/f también se conoce como el recíproco del achatamiento.
