Comparison of galaxy sizes measured from simulated CEERS images, bias-corrected sizes, and intrinsic sizes. The top two rows present results for Petrosian radius (R_p). The middle two rows present results for half-light radius obtained through non-parametric method (). The bottom row presents results for half-light radius obtained through Sérsic fitting (), with no correction applied. The mean difference (Δ) and scatter (σ) between the x-axis and y-axis values are indicated at the top of each panel. Columns one through four show results for z = 0.75, 1.5, 2.25, and 3.0, respectively.
