Cross-correlation function of the HERMES spectrum of WDS 19255+0307Aa,Ab (obtained at JD 2 455 657.742) with a F0V template. Component Aa shows a rotationally broadened profile with V_rsini = 84 km s^-1, and component Ab is visible as a weak Gaussian (at V_r(Ab) = –37.70 km s^-1) superimposed on the rotationally broadened profile (centred on V_r(Aa) = –26.68 km s^-1). Similar profiles have been observed over several consecutive nights.
