Example of computed spectrum (red line) displaying Mn iii lines not observed in the stellar spectrum (black line). The lines are those at 1605.126 Å, 1605.545 Å, and 1605.690 Å. Their upper level is an even level with energy 179 152.090 cm^-1, 172 682.640 cm^-1, and 172 451.230 cm^-1, respectively. The labels for the lines include the last three digits of the wavelength, the code (atomic number) for the element and ion, the lower energy level in cm^-1, and the residual intensity at line center in per mil.
