We show that these coefficients are far from bring negligible as given the level of truncation of 0.1 mu as which is necessary in the reconstruction of the tables of nutation, and also that their value is very close to that given by Bretagnon st al. (1997).engjournal articlehttps//doi.org/10.1023/A:1008298122976http://www.springerlink.com/content/p004831g80371110/fulltext.pdfrestricted access528Non-zonal degree 3 harmonicsDiurnal and sub-diurnal nutationsGeodesia2504 Geodesia
