The largest term in the difference TDB-TT being 1.7 ms $\times \sin l'$, where l' is the mean anomaly of the Sun, the resulting error in the precession quantities using TT is periodic with an annual period and an amplitude less than 10 nanoarcseconds, which significantly exceeds the required accuracy.
