Table 4: 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 1982).
