Stellar mass (${\mathrm{M}}_{\star ,\mathrm{infall}}^{\mathrm{sat}}$) of the two main contributor satellites (SHMCs) to the stellar halo as a function of the stellar halo mass. The upper panel is color-coded by the percentage mass contributed by the SHMC to the accreted stellar halo (M_acc), the middle panel is color-coded by the infall redshift of the satellite (${\mathrm{z}}_{\mathrm{infall}}^{\mathrm{sat}}$), and the lower panel is color-coded by the disruption redshift ($z_{\mathrm{disr}}^{\mathrm{sat}}$). In some galaxies, the main contributor is a surviving satellite which is denoted by open circles. The dashed line represents the 1:1 line, while the solid line indicates the linear regression.
