Abstract Asymmetries, including a blueshifted core asymmetry, are measured in the spectral line profiles of the F5 IV-V star Procyon. Amplitudes of the asymmetry are proportional to line strengths, and characteristic widths change modestly with line strength, ranging from 2.5 km/s to 3.5 km/s. The scaling of asymmetry amplitude with line strength implies that all lines have approximately the same shape regardless of their strength.
