NIR-to-X-ray peak ratio vs. amplitude of the NIR flares. Squares refer to the flares reported in Table 3 of Eckart et al. (2012b). Triangles are the simultaneous NIR/X-ray flares detected on 2007 Apr. 4 and labeled D and E in Table 2 of Trap et al. (2011). Diamonds are the delayed flares of 2004 Jul. 7, 2008 Jul. 26+27 and 2008 May 5 reported in Table 2 of Yusef-Zadeh et al. (2012). The labeled points are the NIR and X-ray flares observed during this campaign.
