Observation-to-model ratios vs. heliocentric distance for (3) Juno using the ADAM model. Although there is a slight curvature in the plot, it shows that with reasonable accuracy we can fit data taken at different temperatures with a constant thermal inertia. The more scattered points at about 2.2 au are IRAS data, which did not have a strong weight on the fit given their significantly larger error bars. Appendix A.3 provides further discussion.
