The whole spectrum obtained for γ Equ. Black line corresponds to the average of the IUE spectra and to the Kharitonov et al. (1988)’s spectrum. For wavelengths λ < 1854 Å and λ > 7390 Å, the figure shows the curve obtained using the interpolation method (dark gray line), the Kurucz model that best fits the spectroscopy in the visible and the photometry in the infrared when models are calibrated with the star’s magnitude m_V (gray line) and when models are calibrated with the relation (R/d)² (light gray line). The Geneva and infrared photometry from Table 4 (circles) and Johnson UBVRI photometry (triangles) are overplotted to the spectrum.
