As Fig. 3, the observed spectrum of the Z06-star can be seen in black. The line mask placements for the Mo (left) and Eu (right) line can be seen in turquoise and the continuum placements in yellow. The best fit to the synthetic spectrum is shown with a solid red line and the ±0.1 dex with a shaded red. Note that the wavelength region is zoomed in compared to Fig. 3 to better show the fit of the synthetic spectrum.
