Comparison of the spectral index α_ox with the Eddington ratio (λ_Edd). The AGN sample from Lusso et al. (2010) is represented in red, the LLAGN sample from Xu (2011) is in yellow, and our modeled values for each LLAGN source are in gray. Our binned data are depicted as blue diamonds, while the black crosses represent the binned data from Lusso et al. (2010). The dashed blue line indicates the fit to all the binned data. Contrary to the anticorrelation proposed by Xu (2011), our fit follows a constant value for the low regime. Shaded regions indicate the 1-sigma uncertainties.
