the visible ($\overline{B_J} = 18.7$~mag versus $\overline{B_J} = 19.8$~mag)

\tablefoottext{b}{There is an additional visual companion to star No.~04.
It is a faint, blue source at $\rho \sim 4.1$~arcsec, $\theta \sim 217$~deg,
only resolved by 2MASS and UKIDSS ($J  = 16.43\pm0.10$~mag), with similarly 
low proper motion.}\\
\tablefoottext{c}{UKIDSS $J$-band magnitude transformed into the 2MASS one by 
adding the offset $J_{\rm 2MASS} - J_{\rm UKIDSS}$ measured for Mayrit~1610344.
There are two additional visual companions to this star:
USNO-A2.0~0825--01615246, a relatively blue star at 7.8~arcsec to the southwest
and with a proper motion ($\mu_\alpha \cos{\delta}$, $\mu_\delta) = 
(+2.9\pm1.2$, $-7.6 \pm0.7$)~mas~a$^{-1}$, and a faint red source at about 
3~arcsec to the southeast only resolved by UKIDSS ($K \approx 16.3$~mag).}}
