Spectral atlas of the Galactic Wolf-Rayet stars (WN sequence).

Spectra of 62 (i.e. almost all) Galactic single Wolf-Rayet stars of the WN sequence are compiled. These data provided the empirical basis for our comprehensive spectral analyses of these stars published recently. The observations cover wide parts of the visual range and have a spectral resolution λ/{DELTA} λ between 2000 and 3600 in most cases. Infrared observations around 10830A are included for 18 stars. The spectra are preliminary ``rectified'' by division through an estimated stellar continuum. The whole material is displayed in concise plots sorted by spectral subtype in order to provide an overview. Access to the full digital data is offered via anonymous file transfer.
