Caption: Fig. 5.
Portion of the HES spectrum of the planetary nebula IC 5117, where the flux is in units of ergs cm−2 s−1 Å−1, showing the [Cl II] 9123.6 Å emission line. Also labeled in the figure is the [S III] 9068.9 Å transition. Radial velocity and interstellar extinction corrections have not been applied to this spectral scan.
