Notes. The top panel shows the uncertainties on Saturn’s gravity harmonics. The second panel (A-C) displays the predictions of the interior model using REOS3b. The bottom panel (D-F) displays the predictions of the interior model using MH13+SCvH. (a) Error bars of the Cassini Grand Finale gravity measurements from Iess et al. (2019). (b) Flow-induced gravity corrections of Galanti et al. (2019). (c)Flow-induced gravity corrections of Kong et al. (2019).
