... detector

FREGATE continuously records the count rates in 4 energy ranges ([6-40], [6-80], [32-400], and [>400] keV, see Atteia et al. 2002). GRBs outside the FOV have almost no counts below 80 keV, providing a reliable way to recognize the GRBs which are within the FOV of FREGATE, even in the absence of a localization.

... GRB

It is probably useful to note here that GRB 011211 which was initially classified as an X-ray rich GRB was then reclassified as a normal GRB Frontera et al. (2002). The afterglow of this GRB and its redshift z= 2.14 were for some time considered as strong arguments in favor of similar distance scales for normal GRBs and X-ray rich GRBs.
