In the paper "Spectral trends in planetary nebulae: The roles of radiative and shock excitation" we make passing reference to precessing jets within NGC 6543. Dr. L. Miranda has kindly pointed out two prior mentions of possible precession in this source, by Miranda & Solf (1992) and Balick & Preston (1987). We are happy to acknowledge these previous analyses.
