Disentangled spectra of Hα with a central wavelength at 6562 Å, indicated with the vertical black line. Left: disentangled spectra from the 2022 epoch. Right: disentangled spectra from the 2023 epoch. The top of each plot combines the OES observed spectra (blue) and the synthetic spectra from the KOREL radial velocity solutions (red) at different orbital phases. The bottom three green lines show the disentangled lines: the stellar atmosphere, the focused wind, and the Earth’s atmosphere (from top to bottom).
