Radial surface brightness profiles of the dwarf galaxy (TTT-d1) near Malin 2. The g- and r-bands profiles are given in green circles and red squares, respectively. We measure the surface brightness profiles on elliptical isophotes using the Photutils python package (Bradley et al. 2019) and following the method from Junais et al. (2022). We fix the axis ratio and PA for the profile measurements to the g-band values from Table. D.1. The green dashed line and the red dot-dashed lines are the best fit Sérsic models (shown in Table. D.1) independently obtained from the 2-dimensional fitting of the g- and r-band images using GALFIT (Peng et al. 2010), respectively. The profiles shown here have not been corrected for inclination and foreground Galactic extinction.
