For a better interpretation of the observations, we characterize their contribution to the polar motion and we estimate the non-rigid effects, which are at the level of a few microareseconds.engjournal articlehttps//doi.org/10.1023/A:1013290523560http://www.springerlink.com/content/l204823360314540/fulltext.pdfrestricted access52Short period nutationsPolar motionEarth orientation parametersAstronomía (Matemáticas)21 Astronomía y Astrofísica
