Fig. 1


Example spectrum of 70 Vir, spectral type G4 V–IV (x-axis is wavelength in Angstrom, y-axis is relative intensity). Top: full 5290-Å wavelength coverage. The other panels show magnifications of four selected wavelength regions. Top down: numerous Fe I lines around 4250 Å, the Mg I triplet at 5175 Å, the Li I 6708-Å region, and the 8004-Å line region commonly used for 12 C / 13C determination.
