Scientific paper

The establishment of a frame of reference for stellar classification in the UV, independent of temperature, surface gravity, and chemical composition. Of the 1900 spectra obtained by TD-1, 94% can be classified identically as abnormal or normal in the optical and UV regions, at 37 A spectral resolution (= 1850 A/mm dispersion in the optical). At 1.8 A spectral resolution, 17% of stars classified as normal by the MK method are abnormal in the UV.
