We present accurate measurements of the central wavelengths of 4947
atomic absorption lines in the solar optical spectrum. The wavelengths,
precise to a level m s-1, are given for both flux
and disc-centre spectra, as measured in relatively recent FTS solar
atlases. This catalogue modernizes existing sources based on
photographic measurements and provides a benchmark to test and perform
wavelength calibrations of astronomical spectra. It will also permit
observers to improve the absolute wavelength calibration of solar
optical spectra when lamps are not available at the telescope.
