The principle of the method and its advantages are recalled, as well as the works giving such Teff. Although the method is almost model independent, the monochromatic red fluxes play an important part. The resulting Teff depends on the blanketing in the models. The stellar metallicity and gravity have to be known to avoid uncertainties of about 1%. In principle an accuracy around 1% on Teff could be obtained, but the uncertainty on the absolute red flux calibration, due to the unsolved problem of the Vega red flux, prevents this from being achieved.
