Hα profile fits of stars with interſerometric measurements. Left panels: Observational spectra are in black, whereas fitted synthetic Ha lines are represented by red continuous lines. A synthetic profile with −200 K is represented by the red dashed line to provide a view of the sensitivity of the flux along the wavelength axis. Shades indicate the windows of fits without metal or telluric lines. Right panels: Histograms of the temperatures associated to each wavelength bin inside of the windows of the fits. Gaussians fitted to the histograms are represented in black, whose peak centers and 1σ dispersions are indicated in red. They correspond to the determined and their fitting errors.
