<Adam M. Dziewonski> and <Don L. Anderson> coauthored the <Preliminary Reference Earth Model>, a radial model constrained by body waves, free oscillations and global integral measurements.<Preliminary reference Earth model by Adam M. Dziewonski and Don L. Anderson>[Abstract and Introduction: data combination and model construction]{ref}

Combining these data constrains <density> and elastic properties more strongly than wave speeds alone. The result is a reference for comparing observations, rather than a claim that every location has identical structure.
