The data were taken at R = 480\" ($\\sim 41.5$ kpc) and R = 526\" ($\\sim 45.5$ kpc) along the SE major axis. The second moment for a non-parametric estimate of the full velocity distribution is $420 \\pm 23$ km/s and $577 \\pm 35$ km/s respectively. There is intriguing evidence in the velocity profiles for two kinematically distinct stellar components at the position of our pointing. Under this assumption we employ a t","authors_text":"Jeremy D.
