Jet total power (a) and jet radiation power (b) as a function of the accretion disk luminosity. The solid lines are the equality lines. The blazar data (opened symbols) and the fitting lines (dashed lines) for FSRQs are taken from Ghisellini et al. (2010). The open symbols with different colors correspond to blazars with different γ-ray observed luminosities: stars for L_γ > 10^48.5, squares for 10^47.5 < L_γ < 10^48.5, triangles for 10^46.5 < L_γ < 10^47.5, circles for 10^45.5 < L_γ < 10^46.5, and diamonds for L_γ < 10^45.5.
