Distribution of the fractional difference $\mathrm{\Delta }{a}_{\text{obs}}^n/a_{\text{bar},\hspace{0.17em}\text{true}}$, where $\mathrm{\Delta }{a}_{\text{obs}}^n=(a_{\text{obs}}^n-a_{\text{bar},\hspace{0.17em}\text{true}})$, at various resolution levels n = a_{bar,  true}/FWHM. The a_{bar,  true} denotes the intrinsic value. We present the results for the F200W PSF. The averaged fractional difference ($\overline{\mathrm{\Delta }a/a}$) and standard deviation (σ_Δa/a) are indicated at the top of each panel. The vertical dashed black line in each panel marks $a_{\text{obs}}^n=a_{\text{bar},\hspace{0.17em}\text{true}}$.
