Size-luminosity relation based on data compiled in Tables 3 and 4 for HAeBes. Each panel emphasizes a different aspect, as indicated in the legends. Top left: HAes and HBes; the five with new GRAVITY data presented in this paper are highlighted in red. Top right: the HAeBes with Balmer excess measurements above and below the median value (0.07 magnitudes). Bottom left: the HAeBes with spectro-interferometric measurements indicating that the Brγ/Hα emitting region is smaller than the dust emitting region and the ones without such evidence. Bottom right: Group I and Group II sources based on the SED shape. (All panels): triangles indicate upper and lower limits, and the solid and dashed lines indicate the expected boundaries of r_in for an optically thin-MA and optically thick-BL inner gaseous disks, respectively (see text for details).
