Abstract: A Spectroscopic Atlas of Deneb (A2Iae) 3826 – 5212

We present a spectroscopic atlas of Deneb (A2 Iae) obtained with the long camera of the 1.22-m telescope of the Dominion Astrophysical Observatotry using Reticon and CCD detectors. From 3826-5212 A, the inverse dispersion is 2.4 A/mm with a resolution of 0.072 A. The mean signal-to-noise ratio is 1030 at the continuum. The wavelengths in the laboratory frame, the equivalent widths, and identifications of the various spectral features are given. This atlas should provide useful guidance for studies of other stars with similar spectral types. The stellar and synthetic spectra with their corresponding line identifications can be examined at /physics/gulliver/atlases.html.
