Solar spectrum observed with LARS in the 6302 Å region from the disk center (μ = 1.0, purple line) toward the solar limb (μ = 0.3, with decreasing gray scale). The spectra were normalized to the continuum intensity at the disk center and are displayed against the air wavelength in Å. The FTS atlas profile is added in yellow (slight y-shifted by + 0.5% for better visualization).
