The spectrum is plotted in 30 A panels, with begin and end wavelength denoted at the borders.

The vertical blue bars mark those lines which have been measured.

The red line marks the sky spectrum divided by 10.

Red dots mark the line identifications from the Keck atlas (Osterbrock et al. 1996 PASP 108, 277 and Osterbrock et al. 1997 PASP 109, 614).

Crosses mark the positions of identified OH lines (Lidman et al. 2000). Positions beyond 9975 A are taken from the Rousselot et al. 2000 (A&A 354, 1134) list. All positions have been transformed from vacuum to air using the Edlen formula.

The squared plus marks artefacts due to a leaking column.
