Luminosity scalings for the WISE samples of the Low-z and High-z quasars with S/N_{W3& W4} > 3. The top panel shows log L_IR vs log L_agn, the middle panel log CF vs log L_agn, and the bottom panel log CF vs log L_IR. The blue circles indicate Low-z quasars, whereas the green and red diamonds indicate High-z sources. The yellow circles and red diamonds indicate Low-z and High-z quasars with the Spitzer M24 data. In the top panel the blue line denotes the Bayesian regression for the data with S/N_{W3& W4} > 3, the orange line is the Bayesian regression for the Spitzer data from both Low-z and High-z subsamples, and the black line is the 1:1 relation between the L_IR and L_agn.
