Examples of identified lines for a Solar-like spectrum at R = 20 000. The elemental spectrum, i.e. the flux computed with the contribution from atomic lines from only one ionization stage of one element, is plotted in red. The full spectrum containing all of the elements and molecules is shown in black. The element and ionization stage associated to the line are noted on the upper left corner of each plot. The central wavelength of the identified line, λ_c is plotted as a vertical dashed grey line. The blue-end and the red-end of the line are plotted as vertical dashed green lines. The depth of the line in the element spectrum is indicated at the bottom left corner of each plot. The purity factor for the entire line is written at the middle-top of the plots. The blue-wing and red-wing purities are enclosed within the line at its left and right, respectively.
