Table 1: Comparison between constants used for different determinations of the dynamical flattening (H): (1) the precession rate in longitude ($\psi _1$); (2) the speed of the general precession in longitude (p1); (3) the geodesic precession (pg); and (4) the obliquity of the ecliptic at J2000.0 ( $\epsilon _0$). The observational value actually used for each study is written in bold.
