Notes. Correlation tests for bar properties and proxies of AGN activity are summarised. The following properties are used to estimate the strength of the bar: Semi-major axis of the bar (abar) normalised by the disc scale length (h), effective surface brightness of the bar (μe, bar), effective surface brightness of the bar normalised by central surface brightness of the disc (μ0). All of these properties are shown in g-, r-, and i-band. The Bar/T (lum.) ratio, ellipticity (ϵ), bar boxiness (c), and ϵ × c are also shown in i-band. The bar properties are tested for correlation with AGN activity proxies, such as the log[O III] luminosity in solar units, log[O III] normalised by fibre luminosity, and accretion parameter ℛ (Heckman et al. 2004). For each test, the correlation coefficient and the significance are shown.
