Notes. All values are quoted at the 99.7% confidence level, with those in brackets indicating the 50% level. Dashes indicate regions where the observation lack sensitivity. A cross (x) marks systems with no detected gaps and no significant proper motion anomaly (PMa). Upper limits are provided for three scenarios: a planet carving the disc’s inner edge, a planet located at the gap(s), and a planet responsible for the PMa. (a)Deeper mass upper limit observed in gap location with JWST – MIRI F1140C: 2 MJup (3σ); Bendahan-West et al. (under review). (b)Deeper mass upper limit observed in gap location with JWST – MIRI F1140C: 3 MJup, 1.8 MJup (3σ); Bendahan-West et al. (under review). (c)Deeper mass upper limit observed in gap location with JWST – MIRI F1140C: 5 MJup (3σ); Bendahan-West et al. (under review). Planet references: (1)Hinkley et al. (2023), (2)Brandt et al.
