  $^{a}$ {The stellar secondary is referred to as ``/C'' in order to avoid confusion with the notation of the planetary companion, which is referred to as an appendix ``b'' to the host star's name in many publications.}
  $^{b}$ {Uncertainties of apparent magnitudes are estimated to be $\delta\rm{mag}=0.10$ (see Sect.~\ref{spt}).}
  $^{c}$ {Separation and period estimates use distances from Table~\ref{tab2}.}
  $^{d}$ {Periods are order-of-magnitude estimations and hence do not include an uncertainty estimation.}
