Abstract

We present a high resolving power ($\lambda$ / $\Delta\lambda$ = 90,000) and high signal-to-noise ratio ($\sim$700) spectral atlas of Vega covering the 3850 -- 6860 \AA wavelength range. The atlas is a result of averaging of spectra recorded with the aid of the echelle spectrograph BOES fed by the 1.8-m telescope at Bohyunsan observatory (Korea). The atlas is provided only in machine-readable form (electronic data file) and will be available in the SIMBAD database upon publication.
