Section of the STIS observations (gray) compared with synthetic spectra. Top: G191−B2B (blue, thin: Tc mass fraction 1.0 × 10-6, red, thick: 1.0 × 10-4). Bottom: RE 0503−289 (blue, thin: 1.0 × 10-5, red, thick: 1.0 × 10-4). The synthetic spectra are convolved with a Gaussian (FWHM = 0.01 Å and 0.06 Å for G191−B2B and RE 0503−289, respectively) to match the resolution of the observations. The strongest photospheric lines are identified.
