Notes. All times are in seconds after the start of the burst, unless noted otherwise. (a)This data coverage is continuous. The rest of the XRT data beyond 5713 s are short intervals with count rates below 9.5 c s−1; (b)this data coverage is continuous. The rest of the XRT data beyond 5007 s are short intervals with count rates below 30 c s−1.
