The International Astronomical Union at its XVIth General Assembly in Grenoble in 1976, accepted (Resolution No. 1 ) a whole new consistent set of astronomical constants recommended for reduction of astronomical observations, and for computation of ephemerides. It superseded the IAU's previous recommendations of 1964 (see IAU (1964) System of Astronomical Constants), became in effect in the Astronomical Almanac from 1984 onward, and remained in use until the in…
