Accretion luminosities estimated from the contrast curves, and using four different relations given in Eqs. (2)-(5) (see text). These four relationships are represented with different colors as described in the upper right panel of the figure. The dotted lines correspond to all the individual objects observed in this work and in Zurlo et al. (2020), while the thick solid lines represent the results for RXJ1615 (as an average case) to highlight the difference between the four models. We represent the estimated L_acc values for planets PDS70b (starred symbols) and PDS70c (filled circles) using the four models. For completeness, we include the L_acc value of PDS70b estimated by Zhou et al. (2021) using a slab model (black star). The corresponding M_acc values for planet PDS70b, assuming a planet mass of 1 M_Jup and a planet radius of 1.75 R_Jup, are displayed on the right y-axis.
