Description:
We set new limits on the mass of the Milky Way, making use of the
latest kinematic information for Galactic satellites and halo objects.
Our sample consists of 11 satellite galaxies, 137 globular clusters,
and 413 field horizontal-branch (FHB) stars up to distances of 10kpc
from the Sun. Roughly half of the objects in this sample have measured
proper motions, permitting the use of their full space motions in our
analysis.
The field horizontal branch stars presented in table1 was created from
the list of Wilhelm 1999 (J/AJ/117/2329) as the source of magnitudes,
radial velocities and [Fe/H]; the proper motions were extracted from
one or more proper-motion catalogs: STARNET Catalog (Roeser 1996),
Yale-San Juan Southern Proper Motion Catalog (SPM 2.0: Platais et al.
1998, Cat. I/283), Lick Northern Proper Motion Catalog (NPM1: Klemola
et al. 1994, Cat. I/199), and TYCHO-2 Catalog (Hog et al. 2000, Cat.
I/259).
