Disentangled spectra of Hβ with a central wavelength at 4860 Å, indicated with the vertical black line. Left: Disentangled spectra from the 2022 epoch in the hard X-ray spectral state. Right: Disentangled spectra from the 2023 epoch in the soft X-ray spectral state. The top of each plot combines the OES observed spectra (blue) and the fit by the separated spectra of the components (red) at different orbital phases. The green line shows the disentangled line from the star’s atmosphere. We do not detect the focused wind spectral component.
