Left: SPHERE 1D projected contrast curves for ANDROMEDA/IRDIS data in the H2, K1, or K_s filter, depending on the observing mode given in Table 2. The results are shown down to the edge of the coronagraph(~100 mas). Centre: corresponding ASDI/IFS magnitude limits for the inner regions. Right: median mass detection limits assuming the initial luminosities given by the AMES-DUSTY, BEX-HOT, and BEX-WARM models. To convert the semi-major axis to au, a median distance was adopted in our sample of ~145 pc. Thick curves correspond to the ANDROMEDA/IRDIS performance, while the shaded areas show the median sensitivities for the upper and lower limits on the age of the companions. ASDI/IFS mass limits are shown in the same curve style up to ~0.8′′. Individual deprojected detection limits are given in Appendix B.
