Disentangled spectra (top panel), bias (middle panel) and polynomial fits to the bias (smooth lines), and corrected spectra (bottom panel). The spectra shown in black and red correspond to component A and B, respectively. For the corrected spectra the fits to the bias were simply subtracted. The top spectrum of the bottom panel is a synthesis calculated with Teff = 6800 K, log g = 3.2 and solar metallicity (violet line). The dashed horizontal lines indicate the continuum. The individual spectra are shifted for better visibility. A colour version of this figure is available online.
