Sample of 1000 model orbits fitted on the HD 167665B data (red points) from RV (top left) and imaging (top right) using the BINARYS tool (see text). The sample was drawn from 10 000 MCMC solutions (Appendix B). The solution derived by the TMB algorithm is shown as green dots. The RV and HIPPARCOS IAD residus (left, from middle to bottom) and the imaging residus (right, from middle to bottom) are computed with respect to the TMB solution.
