Notes. Column 1 indicates the element and its ionisation state; Cols. 2 and 3: air and vacuum wavelengths; Col. 4: lower excitation potential which comes from GES line list; Col. 5: log(gf) from the GES line list, whereas Col. 6 provides our calibrated value. The * close to the air wavelengths indicate that they were slightly modified compared to those given in GES. The spectral lines are ordered by increasing atomic number and increasing wavelength for each atomic species. The full table is available in electronic form at CDS.
