Spectral fitting.

Primary Secondary/hot source
Teff (K) ≤11040 ≥51513
logg; g (g cm−2) 4.1 4.0
vrot (km s−1) 9.1 800
lr 0.57 0.43

Notes. lr is the relative contribution of bolometric fluxes of the companions to the total bolometric flux. The extreme rotation velocity of the secondary component simulates the additional hot continuum.
