The ratio of the number of targets for stacking and all galaxy numbers. The black line is the total number ratio for all member galaxies, and the blue, green, and red lines are the low-, medium-, and high-mass bin galaxy members. We denote the number of stacking targets and the total number of galaxies in each mass and radius bin near the ratio.
