Broadband SEDs for the six TANAMI blazars. Filled data points are from the IceCube integration period (May 2010–May 2012), open circles are archival data outside the time period. Gray shows the absorbed (X-ray) and reddened (optical/UV) spectra. The data have been parametrized with logarithmic parabolas (dashed red lines) modified by extinction and absorption, as well as by an additional blackbody component where necessary (solid black lines).
