Abstract — A Spectroscopic Atlas of o Pegasi (A1 IV) 3827 – 4882

We present a spectroscopic atlas of the sharp-lined, hot metallic-line star o Pegasi (A1 IV) based on spectrograms obtained with the long camera of the 1.22-m telescope of the Dominion Astrophysical Observatory using a Reticon detector. For lambda 3826-4882 the inverse dispersion is 2.4 A /mm with a resolution of 0.072 A. At the continuum the mean signal-to-noise ratio is 800. The wavelengths in the laboratory frame, the equivalent widths, and the identifications of the various spectral features are given. For studies of similar stars and for atomic physicists interested in improving atomic line parameters, this atlas should provide useful guidance. The stellar and synthetic spectra with their corresponding line identifications can be examined at /physics/gulliver/atlases.html.
