Example of the continuum-normalized LAMOST spectrum of KIC 7273199 in three spectral regions (dots). The best template found by ROTFIT for each spectral region is overplotted with a thin red line. The difference between the two spectra is shown in the bottom of each panel with a blue full line. The spectrum is clearly reminiscent of a warm (F-type) star. However, the asymmetry in the red wings of the Balmer Hγ and Hβ lines, can be due to a spectroscopic companion.
