Rest frame SED of the quasars 3C 249.1 (top) and 3C351 (bottom). Data are from the NASA/IPAC Extragalactic Database (NED), Spitzer/IRS (Leipski et al. 2010) and Herschel (Table 2). A fit using a pure AGN is shown on the left and for a combination (black line) of AGN (red line) and starburst (blue dashed) activity on the right. A synchrotron component (yellow dots) is added to better match the near-IR. Model parameters are given in Table 3.
