Notes. Parameters are given for the EPIC pn instrument. Source coordinates are taken from the 3XMM-DR6 catalogue (Rosen et al. 2016) and were also determined in this work using SAS 15. A bore-sight correction using three QSOs was applied to the coordinates determined with SAS 15 for observation 0741800301 (see Sect. 3.2.2). 3XMM J051259.8−682640 was not covered by MOS1 during observation 0690742601 nor by MOS1 or MOS2 during observation 0690742301. Similarly, 3XMM J051034.6−670353 was not covered by MOS1 in either observation. For our spectral and temporal analysis of 3XMM J051034.6−670353 we do not consider the MOS data owing to the low efficiency in the soft band.
