HET spectra of 15 of our PG1159-type central stars (blue graphs), ordered by decreasing Γ_cff. At each spectrum we give the PN name and the spectral type. Overplotted in red are the best-fit models, whose parameters are indicated (Γ_cf, log g, metal abundances in mass fractions). Photospheric, interstellar, PN, telluric, and sky lines are marked, as well as detector artefacts. Distortions in the continuum levels around 4645 A are due to the splice between the UV and Orange spectrograph channels (see text).
