Scientific paper

We present a digital spectral atlas of Vega covering from violet to the near-IR region (˜3900-8800 Å), which has such a high resolution (R ˜ 100000) and high signal-to-noise ratio (typically ˜ 1000-2000 on the average) as to allow a detailed line-profile analysis. In addition, theoretically simulated spectra and lists of lines predicted to have appreciable strengths are also provided, which may be useful for identifying or searching lines on the atlas. Besides, the spectra of Regulus (a representative rapid rotator) obtained at the same night are appended as a reference of telluric lines.
