Evaluation of biases and uncertainties in measuring Petrosian radius (R_p; left), half-light radius using a non-parametric method (; middle), and half-light radius through Sérsic model fitting (; right). The top row illustrates the difference between the measured and intrinsic values as a function of R_p, True/FWHM, with the solid horizon line marking the mean difference. The middle row displays the correlation between the corrected and intrinsic values, with the one-to-one relation indicated by a dashed line. The bottom row presents the fractional uncertainties, together with their best-fit functions plotted as solid lines.
