Methodology for measuring fundamental parameters and associated uncertainties for middle and cool main-sequence stars

• We have performed a study of a representative group of main-sequence stars in the temperature range 5000-10000 K in order to test our methodology for determining fundamental parameters and for the assesment of associated uncertainties. The stars selected have reasonably well-established parameters. This paper presents all the steps of our method, from the selection of spectral intervals and atomic/molecular data, to the determination of effective temperatures, surface gravities and metallicities.
