High-resolution disentangled spectra of both components of the binary system HD 93343 (first two solid black lines). Features that are relevant for spectral classification are indicated. Some artifacts appear on the spectrum of the secondary component, mostly in the wings of hydrogen lines that originate in the disentangling process. In the lower box we present the primary component degraded in resolution and overplotted with the O7.5 Vz standard star from Maíz Apellániz et al. (2016, red dashed line).
