Example spectra for different stars. From top to bottom: spectrum of a Be star (green), a B star (yellow), a BSG (blue), and an RSG (red). Our automated normalization mechanism was not applied to the RSG; it was normalized manually. The estimated V-band magnitude is given for each star. Important diagnostic lines are indicated. The gray shaded region indicates the wavelength region that is blocked by the sodium filter. The spectra are not corrected for tellurics.
