Fig. 1
Our canonical barium-star e − log P distribution. Darker greyscale/colour indicates a greater number density of systems. The plus symbols + are the observations of Jorissen et al. (1998) without the triple system BD +38°118, the diagonal crosses × are the latest HERMES observations (Dermine & Jorissen, in prep.) and the square □ is 56 Uma (Griffin 2008). Where points are joined by lines there are multiple possible orbital solutions.
