Stellar radial velocity standards offer a reference at the level of a few hundred m/s and are not adequate for most present needs. We aim to show that sunlight reflected by asteroids is a fairly accessible way to record a high-resolution solar spectrum from the whole disk, which can therefore be used as a radial velocity standard and can improve the uncertainties of solar line positions. Description: The present solar atlas provides with 491 line wavelengths in the range 540-690nm and 222 lines in the range 400-410nm obtained from Ceres reflected solar spectrum with HARPS. For each line the measured wavelength, the errors returned by model fitting of lines, the Chi square of the fit, and the ion which originates the line are given. File Summary:
