Notes. Coordinates and spectral types are taken from SIMBAD, R-magnitudes are taken from the NOMAD catalog (Zacharias et al. 2004)for HD142527 and HD169142, from the APASS catalog (Henden et al. 2016) for HD135344 B, and from the UCAC4 catalog (Zacharias et al. 2012) for the other targets. Distances are from Gaia data release 2 (Gaia Collaboration 2018). The ages – from top to bottom – are taken from Fairlamb et al. (2015), Müller et al. (2011), Weinberger et al. (2013), Grady et al. (2007), and Meeus et al. (2012).
