Comparison of SFR_norm vs. L_X when the stellar age is free and fixed during the SED-fitting process, for the X-ray AGN within 0.5 < z < 1.5. SFR_norm remains constant at L_{X,2−10 keV} < 10⁴⁴ ergs⁻¹ and increases at higher L_X in both cases. However, SFR_norm values are higher by ∼17% on average when the stellar age is fixed in the SED-fitting process. Errors are estimated via bootstrap resampling. The dashed horizontal line indicates the SFR_norm value (=1) for which the SFR of AGN is equal to the SFR of star-forming galaxies.
