Spectrum of HS 0105+1619. The upper panel shows the low‐resolution flux‐calibrated spectrum obtained with the Kast spectrograph. The lower panel shows the flux‐calibrated HIRES spectrum. The flux calibration was noisy at wavelengths less than 3800 Å and was not applied to the Lyman limit, which is not shown above for the HIRES spectrum.
