Notes. The different works have been labelled as follows: J08 (Jurić et al. 2008); S11 (Sesar et al. 2011); D11 (Deason et al. 2011); dJ10 (de Jong et al. 2010); Ch01 (Chen et al. 2001); B08 (Bell et al. 2008); F14 (Faccioli et al. 2014); and S10 (Sesar et al. 2010) and W09 (Watkins et al. 2009) as reanalysed in F14. The fitted models in F14, S10 and W09 have fixed oblateness and test two different values motivated by the previous findings in S11 and D11.
