Na abundances of first generation stars as a function of different globular clusters’ parameters, namely: semi-major axis (a) of the globular cluster orbits, the eccentricity of the globular cluster orbits, space velocity components V_ϕ and V_θ, V² = , core radius (r_c), half-mass radius (r_h), Jacobi radius (r_J), age to half-mass relaxation time ratio (age/t_h), globular cluster mass, and ratio of the mass lost by tidal disruption to the total globular cluster mass (M_dis/M_ini).
