Fig. 7
Distributions of hard (left panels) and total (right panels) hardness ratios. Observed HRs: black shaded histograms. As a comparison, we show the HRs expected for jet-dominated (Γ = 1.4, blue shaded histogram), and disk-dominated emission (Γ = 1.9, red shaded histogram). The HRs distributions have been calculated for RL (upper panels) and non-RL sources (excluding the non-classified objects; lower panels).
