Simultaneous spectral energy distributions of 3C 345. The blue points indicate the high state of 2009 October 4 (2009B flare), while the red points indicate the low state 2016 June 26. The blue and red solid lines are the best fit with a polynomial curve for high and low state, respectively. The light gray triangles are retrieved from the public archive of the ASI SSDC SED builder tool, the light gray stars are derived from the 70-months BAT all-sky hard X-ray survey (Baumgartner et al. 2013).
