JEM-X light curves (3–25 keV) of the four SWT pairs studied in this work. In the four cases, the primary bursts are brighter than the secondary bursts. The secondary bursts do not display the long exponential tails detected in the standard bursts in this work, indicating a lower H content in the burning fuel. The parameters for the bursts in these pairs are provided in Table 2. a) SWT I; b) SWT II; c) SWT III; d) SWT IV.
