The normal gravity formula and the polar flattening according to geodetic reference system 1967

We computed the values of flattening / of the equipotentialellipsoid of the Earth's field and of coefficients of the normal gravity,according to the Earth's parameters adopted by the International Unionof Geodesy and Geophysics at its General Assembly of 1967 taking intoaccount the mass of atmosphere and using the closed formulae of the Pizzetti-Somigliana theory that appear in: M. Caputo " The Gravity Field ofthe Earth from classical and modern Methods", Academic Press, 1967.
