Disentangled spectra of the secondary and primary components of 9 Sgr in the 4450−4750 and 5580−5890 Å regions. The normalization of the spectra is with respect to the level of the observed spectra and the primary spectrum is shifted vertically by 0.1 continuum units. Note that we excluded some parts of the yellow spectrum that are affected by strong diffuse interstellar bands. Note also that, because of the low RV amplitudes, there are a number of artefacts, such as the wings of strong and broad lines that are not well represented.
