Notes. The celestial coordinates are taken from Harris (1996, 2010 edition). Column 4 gives the metallicity of the cluster (from Roediger et al. 2014). Column 5 gives the central concentration c = log 10(rt/rc), where rt and rc are the tidal and core radii, respectively (from Harris 1996, 2010 edition).
