The effects of some short-period tidal and nutational terms in the observations of the Herstmonceux PZT have been re-examined using observations that extend over a longer period and have been re-reduced using improved catalogue positions. Analytic smoothing of these data has furnished observational residuals that reveal very clearly the effects of short period terms with relatively small amplitudes.
