Caption: Fig. 10.
Same as Fig. 8, but for the 25 pc sample split into companions to lower mass hosts (﹩M_{1}< 1\ M_{\odot }﹩) and companions to higher mass hosts (﹩M_{1}\geq 1\ M_{\odot }﹩). The lower mass hosts have 4.2% planetary, 0.0% brown dwarf, and 11.8% stellar companions. The higher mass hosts have 6.6% planetary, 0.0% brown dwarf, and 9.4% stellar companions. The Doppler method should preferentially find planets around lower mass stars where a greater radial velocity is induced. This is the opposite of what we observe. To aid comparison, both samples are scaled such that they contain the same number of companions as the full corrected less biased 25 pc sample of Fig. 8.
