000002509 520__ $$aHD 92024 (=V381 Car) is an SB1 eclipsing binary system with a ß Cephei star as primary component.  We report on the progress of a combined photometric and spectroscopic investigation of this binary, being the only one of its kind known in the southern hemisphere. Pulsating components of spectroscopic binaries often introduce substantial line-profile variations in the spectra that hamper the determination of orbital radial-velocity amplitudes, and thus also of the stellar masses. Here, in order to minimise the bias from line-profile variations on the orbital RVs,  we use selected matched-profile RV differences to derive the orbital parameters. The method is compared to straightforward cross-correlation with an averaged spectrum.
