Contribution

It introduces an improved technique for estimating external errors and produces a mean homogeneous catalog of stellar effective temperatures based on data intercomparisons.

Findings

Estimated external errors of stellar temperature catalogs

Produced a mean homogeneous catalog of 800 stars

Validated catalog accuracy through comparison with independent data

Abstract

Some selected catalogs of the effective temperatures for F, G and K stars are analyzed. By an improved technique we estimate the external errors of these catalogs from data intercomparisons. The values of the effective temperatures 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 effective temperatures, together with their errors.
