TL;DR: In this paper, the spectral types of the two components were determined and the radial velocities (V_rad~23.1, 19.5 km/s) were obtained using optical spectra obtained at the Southern African Large Telescope (SALT) and other facilities located at the South African Astronomical Observatory (SAAO).
