Notes. ⁽¹⁾ 4U 1820-30 data is accumulated only for the upper xenon layers; ⁽²⁾ in spacecraft clock seconds (i.e., seconds since Jan. 1, 1994, 0:00:00.00 UTC); ⁽³⁾ time in seconds since start time; ⁽⁴⁾ For 4U 1722-30 data were taken after the burst because pre-burst data are contaminated by a recent emergence of the spacecraft from the South Atlantic Geomagnetic Anomaly.
