Constraints on the m_p sini and sma of the companions to our targets with RV linear or quadratic trends. Dark grey: possible (mass, sma) domain for the companion given the available RV data, assuming a circular orbit and an orbital period at least equal to our total time baseline. Light grey: extended (mass, sma) domain in the case of orbital periods smaller than our total time baseline can still be considered, given the observation temporal sampling. Red diamonds: previously imaged companions from the literature: HD 16232 – DI from Roberts et al. (2015); HD 185395 – DI from Desort et al. (2009); HD 199254 – DI from De Rosa et al. (2014). Blue dots: companions previously detected with astrometry and/or RV from the literature: HD 82328 – astrometry from Tokovinin (2014); HD 212754 – RV from Griffin (2010), and astrometry from Goldin & Makarov (2007) and Tokovinin (2014).
