Comparison of the posterior distributions using a uniform versus Gaussian prior on log (ɡ) for AB Pic b (v07 vs. v08 model predictions, shown in light blue and purple, respectively). The Gaussian prior mean value is marked with a blue cross on the log (ɡ) axis, based on the BHAC15 and COND03 evolutionary model predictions. We also marked the T_eff predictions with a blue cross, although this was not used as prior information. For comparison, the solar values for [M/H] and the C/O ratio are shown as black stars.
