In order to facilitate the readers work, we present in Tables 3, 4 and 5 the basic parameters available for our GGCs sample.

In Table 3 we give the coordinates, the position, and the metallicity of the clusters: right ascension and declination (epoch J2000, Cols. 3 and 4); Galactic longitude and latitude (Cols. 5 and 6); Heliocentric (Col. 7) and Galactocentric (Col. 8) distances (assuming $R_{\hbox{$\odot$ }}$ = 8.0 kpc); spatial components (X,Y,Z) (Cols. 9, 10 and 11) in the Sun-centered coordinate system (Xpointing toward the Galactic center, Y in direction of Galactic rotation, Z toward North Galactic Pole) and, finally, the metallicity given in Rutledge et al. ([1997]), on both the Zinn & West ([1984]) and Carretta & Gratton ([1997]) scales.

In Table 4, the photometric parameters are given. Column 3 lists the foreground reddening; Col. 4, the V magnitude level of the horizontal branch; Col. 5, the apparent visual distance modulus; integrated V magnitudes of the clusters are given in Col. 6; Col. 7 gives the absolute visual magnitude. Columns 8 to 11 give the integrated color indices (uncorrected for reddening). Column 12 gives the specific frequency of RR Lyrae variables, while Col. 13 list the horizontal-branch morphological parameter (Lee [1990]).

In Table 5, we present the kinematical and structural parameters for the observed clusters. Column 3 gives the heliocentric radial velocity (km s^-1) with the observational (internal) uncertainty; Col. 4, the radial velocity relative to the local standard of rest; Col. 5, the concentration parameter ( $c = \log (r_{\rm t}/r_{\rm c})$); a "c'' denotes a core-collapsed cluster; Cols. 6 and 7, the core and the half mass radii in arcmin; Col. 8, the logarithm of the core relaxation time, in years; and Col. 9 the logarithm of the relaxation time at the half mass radius. Column 10, the central surface brightness in V; and Col. 11, the logarithm of central luminosity density (Solar luminosities per cubic parsec).
