Abstract:
In this third of three parts of MK classifications of the components
brighter than about B=8mag in Aitken's Catalogue (ADS, 1932) new
classifications are given for 546 stars. Included in this section are
15 Ap stars, 33 Am stars, 18 stars with composite spectra, three stars
with shell spectra, and two SB2s.
Description:
Two-thirds of the current spectra were obtained with the Meinel
Cassegrain spectrograph on the Kitt Peak 0.9m telescope, with a
resolution of 2.5Å. The remaining one-third were obtained with the
Cassegrain spectrograph (also designed by Meinel) on the Kitt Peak
2.1m telescope, with a resolution of 0.8Å.

Note (1): ADS NNNNN AAA in Simbad
Note (2): the Hipparcos parallax is used to derive an absolute magnitude,
if the parallax is substantially larger than its error, e.g.
M(π)=-0.7
