| Static-U | 3510.7 ± 0.7 | −32.61 to −36.61 | This work |

Notes. Values are for Req at 1 bar, as used by Helled et al. (2010b) and Nettelmann et al. (2013) based on Lindal (1992) and Jacobson (2009). Wind corrections from Kaspi et al. (2013) are stated, and the range of corrected static J4 shown in bright pink in Fig. 8 is given.
