Caption: Figure 18.
Comparison of parameters derived from the Sonora Diamondback evolution model framework using the hybrid and hybrid-grav models. Each panel shows a 1:1 plot above its residual (hybrid–hybrid-grav) normalized by the standard deviation of the difference. Parameters shown are effective temperature (orange), surface gravity (blue), radius (green), and mass (pink).
