Composite optical–soft X‐ray spectrum for the RQQs and RLQs in our sample (thick solid line). The three X‐ray–weak quasars, and PG 1114+445, which is affected by a warm absorber, were excluded from the composite. The composite uses ⟨α_ox⟩ = 1.482(±0.025) and ⟨α_x⟩ = = 1.69(±0.07) for the RQQs and ⟨α_ox⟩ = 1.445(±0.07) and ⟨α_x⟩ = 1.22(±0.16) for the RLQs. Note that despite the fact that RLQs are brighter at 2 keV, they are fainter at 0.3 keV. The Mathews & Ferland (1987) spectral shape assumes a hard X‐ray power law down to 0.3 keV and a very steep component below 0.3 keV. This spectral shape is inconsistent with the PSPC results. The far‐UV emission can be parameterized as a cutoff power law. The spectrum shown here has T_cut = 5 × 10⁵ K, which is close to the upper limit on T_cut. The Zheng et al. (1996) FUV composites for RLQs and RQQs are plotted in a thin solid line. They suggest that the FUV power law extends into the soft X‐ray regime, with no extreme UV spectral break and no steep soft component below 0.2 keV.
