RS Oph daily SEDs at VHE gamma rays with LST-1 (blue squares), MAGIC (orange diamonds; Acciari et al. 2022), and H.E.S.S. (green empty squares and filled circles for the telescopes CT5 and CT1–4, respectively; H. E. S. S. Collaboration 2022) during the same day interval. From top to bottom, panels a, b, and c correspond to observation-day intervals t − t₀ ∼ 1 d, 2 d, and 4 d, respectively. The best-fit model for LST-1 is displayed as a blue line together with the grey spectral error band.
