Fig. A.1

Light curves at various frequencies. From top left to bottom right panel: γ-ray 0.1–300 GeV from Fermi/LAT, with 1 day time bin [10-7 ph cm-2 s-1] (the horizontal dotted line correspond to a TS = 4 average upper limit of 2.3 × 10-7 ph cm-2 s-1 for a one-day exposure); X-ray 0.3–10 keV from Swift/XRT [c s-1]; UVW2 from Swift/UVOT [mJy]; UVM2 from Swift/UVOT [mJy]; UVW1 from Swift/UVOT [mJy]; U from Swift/UVOT [mJy]. Time starts on 2008 August 1 00:00 UTC (MJD 54 679).
