Notes. Parameters include electron densities, temperatures, distances, sizes (major and minor axes), expansion velocities, Hα fluxes, and 12 CO emission (rms if undetected, Intensity I or spatially integrated Flux F if detected). Telescope codes: N:NRAO 12m; I: IRAM 30m; S: SEST 15m; A: APEX 12m; C: CSO 10m. (a) Assumed value. (b) Size and Hα flux from Corradi et al. (2011). (c)Size used for ionised mass determination. Estimate of molecular mass used a smaller size based on the equatorial ring, 14×7.5 arcsec2 (see section 3). (d)Based on data presented in Wesson et al. (2018).
