Table 1
Saturn’s rigid-rotation gravity harmonics 
, which are derived by subtracting the flow-induced contributions ΔJ2i (Galanti et al. 2019; Kong et al. 2019) from the Cassini Grand Finale measurements 
(Iess et al. 2019).

Notes. The Cassini Grand Finale measurements of Iess et al. (2019) are normalized to the reference radius 60 268 km instead of 60 330 km.
