Caption: Figure A1.
Observed color gradients measured from aperture photometry are consistent with those extracted via forward-modeling techniques. Solid points show the color gradients derived from PSF-matched elliptical annuli, as shown in the top row of Figure 2. The filters used to compute the color gradients are also identical to those in Figure 2. The color gradients derived from single Sérsic profile fits using PYSERSIC (I. Pasha & T. B. Miller 2023) are shown with black-outlined points, while open points show gradients measured from a double Sérsic model.
