Fig. 5
Left: goodness-of-fit (G′′ factor, see text for details) with respect to the spectral type for the comparison of our IRDIFS data of the HD 7449 candidate to spectral templates from various stellar and brown-dwarf libraries; the best fit is shown by a vertical line. Right: best-fit spectrum of Gl 268 (plain red line) compared to the extracted data points (black dots).
