Notes. The last column indicates whether unambiguous QPEs were detected during the exposure (note that in many cases the exposures were too short to secure QPE detection). Texp is rounded and given in ks.
(a)For the 2024 monitoring campaigns by XMM-Newton, Swift, and NICER, we only report the first and last monitoring observation used here, while the number of monitoring observations is reported in parenthesis in the first column.
