Top: Eddy diffusion coefficients for the chemical structure simulations, , retrieved from the standard disequilibrium retrieval (blue circle points) and that with fixed T_int (red circle points; only shown for the planets with masses larger than half Jupiter mass). Also shown are the eddy diffusion coefficients used for both chemistry and cloud simulations in the same-K_zz retrieval (green square points). Bottom: Eddy diffusion coefficients for the cloud structure simulations, , retrieved from the standard disequilibrium retrieval (purple triangle points), equilibrium retrieval (orange triangle points), and disequilibrium retrieval with fixed T_int (brown triangle points; again, only shown for the planets with masses larger than half Jupiter mass). The eddy diffusion coefficients used for both chemistry and cloud simulations in the same-K_zz retrieval are also plotted (green square points, as in the top panel). The unfilled points indicate our hot Jupiter samples, while the filled points are the Neptune samples, which we define as masses smaller than 0.1 times the Jupiter mass. The error bars indicate 1σ uncertainty from the retrievals.
