Area of the region emitting the marginally resolved Brγ component plotted as a function of L_*for both the Herbig AeBe and CTTs samples. The number labels of the Herbigs are as in Fig. 1. CTTs data are taken from GRAVITY Collaboration (2022). The number labels of the CTTs are the following: T1: AS 353; T2: RULup (epoch 2018); T3: RULup (epoch 2021); T4: TW Hya; T5: DGTau; T6: DoAr44; T7: S CrA; T8: VV CrA. The dotted and solid lines show the best-fitting line of slope 0.75 ± 0.04 (reduced χ² of 0.14) and slope 1.0 (reduced χ² of 0.25), respectively.
