Observed X-ray and radio flux of HD 168112 as a function of the orbital phase evaluated with the ephemerides of Blomme et al. (2024). The top four panels correspond to the different energy bands in the X-ray domain: soft (0.5– 1.0 ke V), medium (1.0–2.0 keV), hard (2.0–4.0 ke V), and total (0.5–10 ke V). Violet filled symbols correspond to XMM-Newton observations, and the red open circles indicate the ROSAT data. The error bars on the X-ray fluxes correspond to the 90% confidence intervals. The bottom panel presents the 6 cm radio flux data from Blomme et al. (2005).
