Mass profiles of A2029 with radially varying completeness. The black line assumes the completeness is a constant with radius. The red and blue lines assume the completeness decreases from the innermost region to the ourtermost region by 40% and 80%, respectively. Shadow regions present the 1 σ credible intervals. Larger completeness variations show larger uncertainties due to the smaller sample after reducing the effective number of galaxies at small radii. The vertical dashed and dotted lines mark the positions of r₅₀₀ and R_half, respectively. The variations of the mass profiles due to different completeness functions are well with the 1 σ region, suggesting our results are not sensitive to incompleteness.
