Notes. The first magnitude measurements in J and H bands are given along with the time after the burst when they were carried out.(a)Temporal decay index of the GRB as measured in the frame of the observer. If two values are provided, an associated time break is given (tbreak).(b)Spectral index of the GRB as measured in the frame of the observer. Is assumed to be constant over time. [1] Haislip et al.
