Cavity size diagram for the 11 systems (top) and the corresponding median SEDs (bottom). The cavity sizes are displayed relative to the theoretical dust sublimation radii. The shaded grey area corresponds to the dust sublimation radii with temperatures of 1000–1500 K. The physical sizes of the inner rim radii are indicated for the transition discs assuming Gaia DR3 distances. The categories correspond to the classification of the SEDs by Kluska et al. (2022). The median SEDs of sources in categories 1, 3, and 2 are shown below and indicate the differences in the IR excesses between each category.
