Abstract:
Some selected catalogs of the effective temperatures (Teff) for F, G
and K stars are analyzed. By an improved technique we estimate the
external errors of these catalogs from data intercomparisons. The Teff
values are then averaged with the appropriate weights to produce a
mean homogeneous catalog based on the selected data. This catalog,
containing 800 stars, is compared with some other independent catalogs
for estimating their external errors. The data may be used as a source
of reliable homogeneous values of Teff, together with their errors.
