$^a$ {Optical magnitudes were measured at the Isaac Newton Telescope with the Wide Field Camera; 
$B$ and $V$ filters are from the Harris system, and~$r$ from the Sloan system.}
$^b$  {$J$ and $K$ magnitudes are 2MASS measurements.}
$^c$ {The origin of the estimate for effective temperature (Teff), spectral type and luminosity class (SpT) may be from spectral analysis (HA for HARPS, UV for UVES, SO for SOPHIE) or by default, from multicolour photometry.}
$^d$ {``conta'' is the ratio between the background flux and the total flux.}
