\caption{Fundamental parameters of the studied clusters. The coordinates system
is such that
the $Y$ axis connects the Sun to the Galactic Center, while the $X$ axis is perpendicular 
to that.
$Y$ is positive toward the Galactic anti-center, and $X$ is positive in the first and
 second Galactic quadrants (Lynga \cite{Lyn82}).}\label{t4}
