Planetary mass estimate as a function of the assumed evolutionary track, atmospheric model and age uncertainties for the PDS70b protoplanet. Colors represent the different bands considered here and are reported at the bottom of each band. Markers and their error-bars represent the mass estimates when the age is assumed to be known and exact (τ = 8 Myr, σ_Age = 0 Myr) when using AMES-Dusty (squares), BT-Settl (circles) and BEX-Warm+Cond (diamond). Shaded areas represent the same measurement considering different uncertainties (σ_Age = 3 Myr for the more intensely colored regions, σ_Age = 5 Myr for the more transparent regions). The gray region represents the 68% confidence level range of the value for dynamical mass of PDS70b calculated in Wang et al. (2021) thanks to the astrometric precision of the VLTI/GRAVITY instrument.
