Light curves of PKS 1510–089 during the observation period. a: nightly averaged VHE γ-ray light curve from H.E.S.S. (red points) and MAGIC (green open squares). The grey bars mark the systematic uncertainties. b: 24 h-average HE γ-ray light curve from Fermi-LAT. The dashed line marks the 11 years average with F̅ = 3.92 × 10⁻⁷ ph cm⁻² s⁻¹. Arrows mark 95% CL upper limits for bins with test statistics (TS) < 9.0. c: 24 h-binned HE γ-ray spectral index assuming a power-law spectrum. The dashed line marks the 11-year average with the index = 2.402. d: nightly averaged optical R-band light curve (de-reddened) from ATOM. The horizontal bars mark the observation time.
