Abstract:
A high-resolution spectroscopic survey in the 6380-6460Å region of
224 slowly-rotating M-K class III giants is presented. Spectral
line-depth ratio are calibrated against effective temperature obtained
from B-V and V-I color indices in the range 3200-7500K (M6-A9). A
table of polynomial coefficients for 12 line-ratio-Teff relations can
be used to derive Teff of F-M stars to within 33K (rms), and of
early-F and mid-to-late M stars to within 77-106K (rms).
