Solar spectrum taken using asteroid Vesta during the run at Magellan in January 2006. Spectral lines are listed in order of element and wavelength. Chemical elements with all the hfs lines are indicated inside the lines. The different colored lines represent the different synthetic spectra with different abundances in steps of 0.04 dex, while the dots are the observed spectra. The lower panels show the values of differences between the real and synthetic spectra for the synthetic spectra plotted above. The red lines represent the best fit derived from un-normalized χ², visible in the small plot as a red dot. Here the fits for the Sr line and the five Zr lines are shown.
