Flux-calibrated spectra. The green lines are the binned (factor of 2) spectra with the red lines representing the typical error (obtained by IRAF - routines) of the respective data point. Features stemming from an imperfect sky-subtraction are marked in light gray, significant (5σ in all 3 spectra or 10σ in 2/3 spectra) absorption/emission features originating in the object are marked light magenta/blue.
