Rest-frame 0.3–10 keV luminosity light curves of GRB 090510 (in orange) and GRB 090618 (in blue), the prototypical IGC source. An overlapping pattern has been observed in IGC sources (Pisani et al. 2013), as well as a nesting behavior (Ruffini et al. 2014); it is clear from the deviation between the two light curves that GRB 090510 does not follow this characteristic pattern, thereby confirming its non-IGC nature.
