A Spectrophometric Analysis of Procyon. I. Equivalent Widths and Line Profiles.
Abstract
The equivalent widths of 152 lines (22 chemical elements) and the profiles of Ha, H and Ca ii K meastired from high-dispersion spectrograms of the F5 IV-V subgiant Procyon are tabulated. Various limitations on the accuracy of these results are discussed, including photographic adjacency effects (Appendix I) and scattering of light in the coude' spectrograph at McDonald Observatory (Appendix II).
