Sensitivity curve for HD 148427 companion. The red cross represents the value obtained by Kiefer et al. (2021) using GASTON; the green cross is the value we obtained with GDR3 in this work. Our result is below the sensitivity curve. Since the error of Δν_T is bigger than the value itself, for construction, we cannot represent it because it would show a negative mass. With the hatched area we represent the positive values.
