Notes. We list their coordinates (J2000), J and Ks photometry from VHS, w1 and w2 magnitudes from WISE, proper motions in right ascension and declination (mas/yr) with a typical errors of 15–20 mas/yr in each direction, the name of the associated planet-host star with its spectral type in brackets, the distance of the planet-host star, the separation in arcmin, proper motions of the primary (in mas/yr) with their errors from Hipparcos, and the final conclusion (C?) on the validity of the system. From top to bottom, panels list objects with “Y” which are truly wide common proper motion systems, objects classified as “Y:” that are common proper motion candidates located at very wide separations, and rejected systems marked as “N”.
