Notes. The use of disentangled template spectra leads formally to zero systemic velocities for both components; by comparing the disentangled spectra to rotationally broadened synthetic spectra, we estimated the true systemic velocity of V346 Cen to be −4 ± 3 km s-1. For comparison, GCA obtained −8 ± 3 km s-1 from their two photographic spectra taken in opposite elongations.
