GRB 160131A light curves from radio to X-rays. Yellow shaded areas show the time intervals (centred to 0.8 d, 1.7 d, 2.7 d, and 5.8 d) where SEDs have been empirically analysed. Filled circles indicate detections (uncertainties are smaller than the corresponding symbol sizes), which are connected with each other through a segment, and upside down triangles indicate 3σ upper limits.
