Distribution of count rates obtained from the background-subtracted XMM-Newton/EPIC light curve acquired on 2024 February 8 binned with a time resolution of 20 s. We defined the high modes as the time intervals when the count rate exceeded 0.8 counts s⁻¹ (red dashed line), and the low modes as those when the count rate dropped below 0.4 counts s⁻¹ (blue dashed line). A “transition” region is also present, following the procedure adopted by Bogdanov et al. (2015) for J1023. No flaring mode was observed.
