Time evolution of bound gas mass in the outer region (5 − 10 R_eff) and the inflow gas rate into the inner region 3 R_eff for normal satellites. The evolution of each galaxy is time-aligned such that infall occurs at ΔT = 0. All quantities are normalized to their respective values at the time of infall. The red and blue solid lines show the median evolution of bound mass and gas inflow rate of the galaxies, respectively, while the shaded regions represent the interquartile ranges. Both quantities decrease after infall, reaching 30 − 40% of their initial values at infall, indicating substantial gas stripping in the outer gaseous halos of normal satellites.
