Comparison of the stellar mass surface density profiles of Malin 2 using the TTT data (black dashed line) and DECaLS data (red dash-dotted line). The shaded regions mark the 1σ uncertainty of the profiles. Both the profiles are measured following the same procedure as described in Sect. 3.3. We see that both the profiles agree well, but shows some differences beyond 40 kpc radius which are still consistent within a 3σ level of uncertainty.
