NIR/X-ray peak ratio vs. time delay for the synchrotron-inverse Compton process. The asterisks are the results reported by Yusef-Zadeh et al. (2012), the solid line is a parabolic fit. The horizontal solid line and gray box are the lower limit and error bar on the NIR/X-ray peak ratio of the flare I/1 on 2014 Mar. 10 and the corresponding time-delay range. The dashed line is the ratio between the maximum NIR amplitude reported by Witzel et al. (2012) and the X-ray peak of flare 1, with the gray box being the corresponding error bar (see text for details).
