Evolution of the ``efficiency'' when different data sets are combined into a unified adjustment.

POURBAIX D. and EICHHORN H.

Abstract (from CDS):

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.
