Spectral energy distribution obtained for 78 Vir. The IUE spectrum is shown in black at the lower wavelengths, the ELODIE spectrum is shown in blue, the interpolations are shown in gray and the 2MASS data are shown by orange circles. Spectrophotometric data are shown by blue (Kharitonov et al. 1988), cyan (Adelman et al. 1989), and red (Glushneva et al. 1998) dots. Insets at the top are zooms for two different spectral ranges.
