Section of the HST/STIS spectrum (thin gray line) and a model (thick dashed line) comprising two Ne vii triplets and a singlet with uncertain wavelength positions. Some of the unidentified lines might correspond to the computed ones. Model parameters: T_eff = 200 000 K, log  g= 6.7, Ne = 1.2 × 10^-2. Observation and model were convolved with a 0.02 Å boxcar and a 0.036 Å Gaussian, respectively.
