Detail of the NUV spectrum (thin gray lines) showing the Ne viii 3s−3p doublet. Bottom: overplotted are two models (thick lines) with different temperatures (dashed and solid lines as indicated in the legend) and Ne = 1.2%. Top: same spectrum and a model with Ne = 5% (thick dashed line). Models have log g= 6.7. Observation and models were convolved with a 0.18 Å boxcar and 0.20 Å Gaussians, respectively.
