\tablefoot{If the sdB mass couldn't be constrained with other methods the theoretically predicted mass range of  $0.43{-}0.47~{M_{\rm \odot}}$ was taken from Han et~al. (\cite{han1,han2}). The minimum masses of the companions and maximum inclinations of the binaries were calculated for the lowest possible sdB mass  ($0.3~{M_{\rm \odot}}$, Han et~al. \cite{han1,han2}). {*}~The orbital periods given here are rounded to the second decimal place. The accurate values are given in Table~\ref{orbit}. Additional constraints to clarify the nature of the unseen companions: $^{r}$ The detection of a reflection effect from a cool MS/BD or a $^{n}$~non-detection to exclude  this option. The presence of eclipses $^{ec}$~or ellipsoidal  deformations~$^{el}$ in the light curves. No signatures of a main-sequence companion  within the given mass range are visible in the flux distribution or in the spectrum~$^{f}$.
