Disentangled Aurélie spectra of BD+60° 497. Reconstructed spectra from the 2002−2003 epoch are shown by the blue continuous line for the primary, and the red continuous line for the secondary (shifted vertically by 0.2 units). The black dashed lines represent the result of the disentangling for the 2018−2022 data. The spectra are displayed normalised to the global continuum of the system. The broad double-minimum features around 4502, 4726, 4763, and 4780 Å are artefacts due to the disentangling of the stationary diffuse interstellar bands at those wavelengths.
