Simultaneous UV and soft X-ray Swift observations by Grupe et al. (2010) of two AGN sources Mkn 335 and Mkn 876 (blue and red stars, respectively). Mkn 335 is a pure AGN without significant star-formation activity, whereas Mkn 876 demonstrates both strong AGN activity and intense circumnuclear star formation. The original data by Grupe et al. are (i) corrected for Galactic absorption using the X-ray cross section from Morrison & McCammon (1983) and N(H) from Table 1 in Grupe et al.; (ii) transferred from coordinates log (νL_ν) vs. log ν to log (L_ν) vs. log E; (iii) normalized by L_ν at 1 Ryd, which is found by linear extrapolation of the UV data to 1 Ryd with spectral indices reported for Mkn 335 and Mkn 876 in Shull et al. (2012). The solid lines in the X-ray range are the power laws with indices given in Table 4 in Grupe et al.The dotted lines show the SEDs restored for the z = 1.9410 (blue) and 1.7193 (red) systems.
