Fig. 1.
Long-term light curves of 1ES 1959+650 in 2016 with four instruments. From top to bottom: VHE gamma-ray flux (>300 GeV) from MAGIC, HE gamma-ray flux (0.3–300 GeV) measured with Fermi-LAT, X-ray energy flux (0.5–5.0 keV) from Swift-XRT, and UV energy flux (W1 filter, ∼260 nm) from Swift-UVOT. The flux in Crab Units is indicated with an additional y-axis in the top panel.
