Notes. Masses from M1van Terwisga et al. (2018). L★ and Lacc from L1 Alcalá et al. (2017), L2Long et al. (2019), L3Herczeg & Hillenbrand (2014), L4Donati et al. (2020), L5Gangi et al. (2022), L6Pecaut & Mamajek (2016), L7Skinner & Audard (2022), and L8Manara et al. (2016) scaled to the updated Gaia distance where relevant. All distances from the Gaia DR2 parallax (Gaia Collaboration 2016, 2023). Outer dust and gap radii estimated from ALMA data (see Appendix C). Ages are from A1Andrews et al. (2018), A2van der Marel et al. (2019), A3Müller et al. (2018), and A4 Orihara et al. (2023). Ages are generally very uncertain and may be based on different estimation methods. Especially for Sz 98 and V1094 Sco, we found large discrepancies in the literature, and we assume they are of the order of millions of years old, similarly to the other discs.
