From top to bottom: panels 1–6: UVOT data (w1, m2, w2, u, b, v bands observed flux in units of mJy) acquired during the observations described in Table 1; panel 7: Swift/XRT (0.3−10.0 keV observed flux in units of 10⁻¹² erg cm⁻² s⁻¹); last panel: γ-ray 48 h-bin light curve (>100 MeV observed flux in units of 10⁻⁷ photons cm⁻² s⁻¹), AGILE datain red, Fermi-LAT in black. The only NIR data from OAGH available during this time interval were taken on MJD ~ 57498 (flux density = (2.64 ± 0.10) mJy in J band, (4.16 ± 0.19) mJy in H band, (5.91 ± 0.27) mJy in Ks band).
