\caption{A list of spectral lines used for the stratification calculations. The columns give the ion identification, central wavelength, the excitation potential (in~eV) of the lower level, oscillator strength ($\log~{gf}$), the Stark damping constant ("appr'' marks lines for which the classical approximation was used), and the reference for oscillator strength.}\label{strat-list}
