Notes. We list the name of the star observed with NaCo, the name of the wide companion, the projected separations in arcsec and in AU, the average proper motion of the components, the proper motion difference, the magnitude difference ΔV, the fractional proper motion difference, the ΔX index, the absolute value of the RV difference and the number of components. For high-multiplicity systems, additional remarks are listed. Note on high-multiplicity systems: HIP 8038: close visual binary (VB); TYC 8484-1507-1: close VB and SB2 (likely same companion); HIP 12361: wide companion to TYC 8484-1507-1 and HIP 12326 triple system; HIP 25436: spectroscopic and astrometric binary; HIP 35564: SB; HD 57853: SB3; HIP 46637: SB; HIP 72399: SB; TYC 6786-0811-1: close VB; HIP 77235: triple system but physical link to TYC 6786-0811-1 needs confirmation; HD 199058: close VB.
