The best-fit results and different model components for a lens sample with mass ﹩14.0\leqslant \mathrm{log}{M}_{{\rm{G}}}\lt 14.4﹩ at redshift 0.3 ≤ z < 0.4. The dark and light gray shaded regions represent the 68% and 95% confidence intervals of the total ESD fitting results, respectively. The three panels correspond to the three different types of group center. The different colored lines represent the halo components labeled in the legend. The χ ²/ν value is also provided in each panel. Note that the degrees of freedom have a value of ν = 15 here.
