Description:
MK spectral types are given for about 584 stars in "A Supplement to
the Bright Star Catalogue" (Hoffleit et al., 1983, Cat. V/36). The
spectra were obtained at Kitt Peak in 1983 on Eastman IIaO emulsions,
15% with the Cassegrain spectrograph on the 2.1m telescope and the
rest with a Cassegrain spectrograph on the 0.9m telescope.
The spectral types are compared with Hipparcos parallaxes to check the
reliability of those classifications. The estimated errors are ±1.2
subtypes, and 10% of the luminosity classes may be wrong.
