Notes. Gaia coordinates are for (J2000, epoch 2015.0) and were rounded to 0.000001 degrees. Although the TGAS data may be more accurate, all parallaxes and their errors were rounded to 0.1 mas, proper motions and their errors to 0.1 mas yr⁻¹. The absolute values of measured proper motion differences dpm and the estimated effect because of orbital motion pmo were rounded to 1 mas yr⁻¹. Magnitudes and colours were rounded to 0.01 mag. Spectral types with question marks are only guesses based on G − J and M_G (Figs. 3 and 5). Further notes on the data: ^(a) Gaia DR1, ^(b) 2MASS, ^(c) TGAS, ^(d) UCAC5, ^(e) UPC, ^(f) two values are given for RA and Dec, respectively, ^(g) J magnitude with very poor goodness-of-fit quality of the profile-fit photometry, ^(h) An accurate parallax of 87.4 ± 0.5 mas measured for this close binary by Nelan et al. (2015), ⁽ⁱ⁾Subasavage et al. (2009) measured a parallax of 56.54 ± 0.95 mas, ^(j) this object is not plotted in Figs. 4 and 5, since it was not identified in Gaia DR1.
