Maximum mass of a secondary object that can elude detection in our disentangling approach. The simulations have been run with v sin i = 100 km s⁻¹. These detection limits are given when the secondary is considered as a MS star (top), a stripped helium star (middle), or an inner close binary in a hierarchical triple system (bottom). Middle panel: no markers have been indicated for four systems because we were not able to detect the stripped companion. Bottom panel: the y axis corresponds to the total mass of the inner system.
