• Introduce admittance errors to IERS model at 10 to 20% level<br />
– simulated errors similar <strong>in</strong> magnitude to true model errors<br />
– 71 terms at 12h + 24h periods <strong>in</strong> each 1D component<br />
– <strong>in</strong> 3D, tidal errors beat to higher & lower frequencies<br />
