Abstract:

Using a sample of binaries which were observed visually (VB) as well as spectroscopically for both components (SB2), we show that the efficiency almost always increases when a combined VB-SB2 solution replaces one based only on VB.

Key words: methods: numerical; statistical -- binaries: visual; spectroscopic
