Detection limits on AB Dor at 1.575 μm (orange), 1.625 μm (red) in the top panel and in SDI (blue) in the bottom panel as a function of the separation. The solid lines (analytic) were estimated from a direct conversion of five times the noise into mass with the conversion map for SDI or with standard contrast conversion for single-band images. The limits were also estimated by injecting FP according to the predictions of the model, processed independently, until S/N = 5 was reached (“FP”, dashed lines), with a 1σ dispersion over five position angles (shaded area). The direct conversion from noise to contrast and mass without taking the SDI photometric bias into account, i.e., assuming a T8 SpT, is overplotted (“CH4”, triple-dotted dashed line).
