Stellar masses as a function of ratio between PSF/R_e. The KMOS^3D, KGES, and KROSS samples are represented by red circles, green crosses, and blue stars, respectively, with a vertical dashed line indicating PSF = xR_e. This figure indicates that only a limited number (= 53) of galaxies are applicable for determining the dark matter fraction within R_e. However, it is important to note that our analysis is not restricted within R_e. In fact, we evaluate the dark matter fraction at outer radii (i.e., R > R_e).
