Impact of aperture choice on the extracted SB for a fixed synthetic disc model. Upper panel: SB curves obtained using three different elliptical apertures, compared to the intrinsic SPF. Lower panel: SB curves obtained using three different circular apertures. Each curve is normalised at 90°, and the legend indicates the sampling and aperture size in units of the PSF FWHM (first number and second number, respectively) along with the integrated absolute difference (∆Area; Eq. (1)).
