| Northern inner | 13.3 ± 1.6 | 10.1 ± 2.3 | 19.3 | 3.6 ± 2.0 | 33 | 19 | 74 | 3.6 ± 2.0 |
| Southern inner | 15.5 ± 2.2 | 10.5 ± 3.3 | 25.0 | 3.6 ± 2.4 | 41 | 25 | 78 | 2.9 ± 2.0 |
Notes. For each cavity we list the semi-minor axis (a), semi-major axis (b), distance from cluster centre (R), energy of the cavity (Ecav), buoyancy timescale (tbuoy), sound crossing timescale (tcs) refilling timescale (tref), and power of the cavity (Pcav, buoy = Ecav/tbuoy). The values for the outer and inner cavities are taken from Table 2 of Vantyghem et al. (2014).
