Paper Abstract

This paper presents results on spectral line and profile variability, equivalent widths and line identification for α Cygni (A2 Ia) and ε Aurigae (A8 Ia). The results are based upon photometrically precise spectra obtained with a Michelson-Fourier spectrophotometer. The wavelength interval extends from 0.48 to 1.02 microns, approximately. The spectral resolution is 3.85 cm-1. The analysis has been carried out totally with computers using, both, automatic and interactive techniques. These are briefly discussed.
