Notes. Parameters derived from the XMM-Newton EPIC observations of HD 45166 assuming a three-temperature thermal plasma (VAPEC) model and a thermal (VAPEC) plus a power-law model, both models corrected for the interstellar absorption using the TBABS model. The errors are at 68% confidence level. The abundances are set to those deduced from the spectral analysis of optical and UV spectra of HD 45166 Shenar et al. (2023). The corresponding spectral fits are shown in Fig. 1. The contributions of each spectral component are shown in Fig. 2.
