\begin{table} \par \caption{\label{t:res1}Results of our measurement for program stars: HIP~and HD~names, identification of the component (A, B) date of the observations, radial velocity, $B-V$ color, {\it FWHM} of spectral lines (corrected for instrumental broadening), projected rotational velocity, {\em S} index calibrated on the Mount Wilson scale, chromospheric emission flux, logarithm of age derived from chromospheric activity, and additional remarks. For stars with $v \sin i > 40$~km~s$^{-1}$, only lower limits to chromospheric emission were measured.} %\centering \par \begin{tabular}{cccccccccccl} \hline \hline \noalign{\smallskip} Name & Name & Comp. & JD & $RV$ & $B-V$ & {\it FWHM} & $ v \sin i$ & $S$ & $\log R^{'}_{\rm HK}$ & log age & Remarks \\ HIP~ & HD~ & & $-$2~450~000 & km~s$^{-1}$ & & km~s$^{-1}$ & km~s$^{-1}$ & & & yr & \\ \noalign{\smallskip} \hline \noalign{\smallskip} \object{ 3290} & 4001 & A &2~498.350 & $-$2.73~$\pm$~0.12 & 0.47 & 12.02 & 6.1 & 0.13 & $-$5.21 & 10.05 & \\ \object{ 3290} & & B &2~498.401 & $-$0.81~$\pm$~0.13 & 0.51 & 10.54 & 5.0 & 0.14 & $-$5.14 & 9.95 & \\ \object{ 4540} & 5659 & A &2~500.306 & 0.60~$\pm$~0.36 & 0.47 & 31.26 & 18.2 & 0.22 & $-$4.65 & 9.20 & \\ \object{ 4540} & & B &2~500.326 & 1.83~$\pm$~0.20 & 0.43 & 39.63 & 22.7 & 0.19 & $-$4.76 & 9.37 & \\ \object{ 10175} & 13357 & A &2~500.352 & 25.20~$\pm$~0.11 & 0.67 & 8.21 & 3.1 & 0.23 & $-$4.70 & 9.27 & \\ \object{ 10175} & & B &2~500.393 & 26.01~$\pm$~0.11 & 0.73 & 7.45 & 2.4 & 0.28 & $-$4.61 & 9.14 & \\ \object{ 20552} & 28255 & A &2~720.978 & $-$4.61~$\pm$~0.10 & 0.63 & 7.83 & 2.5 & 0.18 & $-$4.88 & 9.56 & \\ \object{ 20552} & & B &2~720.986 & $-$3.15~$\pm$~0.11 & 0.70 & 7.38 & 2.2 & 0.23 & $-$4.72 & 9.30 & \\ \object{ 20610} & 29058 & A &2~720.994 & $-$0.97~$\pm$~0.21 & 0.47 & 53.63 & 29.6 & 0.31 & $-$4.43 & 8.73 & \\ \object{ 20612} & & B &2~721.003 & 0.20~$\pm$~0.14 & 0.50 & 31.55 & 18.4 & 0.32 & $-$4.41 & 8.64 & \\ \object{ 25436} & 35996 & A &2~721.014 & 32.17~$\pm$~1.30 & 0.41 & & 112 & $>$$0.25$ & $>$$-$4.57 & $<$9.07 & SB1?
