Notes. For the age of the radio lobe (t_rad) derived from our analysis we report a range of values. The highest value is derived with a simple radiative Tribble model fit, while the lowest is corrected for adiabatic losses. The three X-ray cavity age estimates are based on the buoyancy timescale (t_buoyancy), the sound crossing timescale (t_cs), and the refill timescale (t_refill). The southern and northern outer cavity timescales are derived by Vantyghem et al. (2014), while we estimate the timescales for the intermediate cavity reporting a range of values for the different dimensions of the cavity considered.
