Abstract

Zinn & Lee (1994, in prep.) have shown that the halo globular clusters with R gc < 6 kpc are dominated by clusters with relatively blue horizontal branches for their metal abundance, which they interpret as a sign of their old relative ages. Of these “Old Halo” clusters having -1.7 < [Fe/H] < −0.8 dex, they find a net rotation about the galactic center of V rot = 59 ± 22 km s-1, and a line-of-sight velocity dispersion of σ los = 62 ± 10 km s-1.
