A catalogue of accurate wavelengths in the optical spectrum of the Sun
A catalogue of accurate wavelengths in the optical spectrum of the Sun
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 …
