PD, PA, count rate, and hardness ratio (top to bottom) for HS 2022 (blue), IMS 2022 (yellow), HS 2023 (green), and SS 2024 (red) variation with time. HS 2022, IMS 2022, and SS 2024 are shifted for the first superior conjunction of the system during the IXPE observations to coincide with that of HS 2023. The entire 2–8 keV energy band was considered with data binned in intervals of 500 s. For HS 2022, only the first observational epoch is shown here, as the second epoch does not provide additional information beyond previous studies (A. Veledina et al. 2024a).
