Contrast curves derived from PACO, TLOCI and KLIP for a probability of detection PD ∈ {50%;80%} at λ1  =  2.110 μm and λ2  =  2.251 μm for the HD 131399 (2015), HD 131399 (2016) and HIP 72192 datasets respectively. Contrast curves as provided by KLIP and TLOCI do not correspond to a 5σ false alarm rate contrarily to the contrast curves of PACO. The achievable contrasts are thus significantly over-optimistic for KLIP and TLOCI, see discussion in the text (Sect. 5.2).
