Multidirectional photometry of Malin 2. Left: Wedge positions used for the photometry overplotted on the color image of Malin 2. Six wedges, each with 30° opening angles, are positioned at 0°, 60°, 120°, 180°, 240°, and 300°. A radial scale bar (in units of arcsec) is also shown along each wedge for easier comparison with the radial profiles. The location of the candidate dwarf satellite galaxy TTT-d1, discussed in Sect. 3.5, is marked in the bottom left corner (white circle). Right: Corresponding radial profiles of g- and r-band surface brightness for each wedge direction, showing significant structural asymmetry across different orientations. The dashed black line is the classical azimuthally averaged isophotal profile we measured, with the shaded gray region as its uncertainty.
