Observed vs. single power‐law fit PSPC spectra of the 13 quasars not reported in Paper I. The upper panel for each object shows the observed count rate (points with error bars), and the expected count rate using the best‐fit single power‐law model with a free N_H (solid‐line histogram). The middle panel shows the observed minus the expected flux in units of standard deviations, and the lower panel for each object shows the fractional deviations from the expected flux. The best‐fit α_x, the fit χ², and the number of degrees of freedom (dof) are indicated for each object. The spectra of all quasars are consistent with a simple power law. Note in particular the high S/N spectrum of PG 1116+215, where intrinsic features below 1 keV must have an amplitude of less than ﹩\simeq ﹩10%.
