The Influence of Spectral Resolution on Line Blending and Wavelength Positions in the Solar Ultraviolet Spectrum
Abstract
For representative sections of the solar UV spectrum (λ 2765 Å-λ 2790 Å, λ 2765 Å-λ 2805 Å) the line density and the accuracy of wavelength positions of absorption features are derived as function of the spectral resolution. In low resolution spectrograms unresolved blends may shift intrinsic wavelength positions of absorption lines by amounts up to a few tenths of the spectral resolution.
