Comparison between the N-type spectral standard stars RS Cyg (C-N5.5 C₂3, red), Z Psc (C-N5 C₂4, blue), and V460 Cyg (C-N5 C₂4.5, green) from Barnbaum et al. (1996) with the Hermes spectrum of LX Cyg smoothed to the resolution of the atlas spectra (R = 2500, black). The spectra are scaled to have the same maximum flux in the shown wavelength range. Vertical dotted lines indicate the wavelengths of C₂ band heads from the Swan system (Kipper 2004).
