Abstract:
We have obtained moderate resolution (∼6km/s) spectroscopy of several
hundred M giant candidates selected from Two Micron All Sky Survey
photometry (Cat. II/246). Radial velocities are presented for stars
mainly in the southern Galactic hemisphere, and the primary targets
have Galactic positions consistent with association to the tidal tail
system of the Sagittarius (Sgr) dwarf galaxy.

Note (1): Derived from the Equinox 2000.0 coordinates. These star names have
been generated with our own software and may differ slightly from
the official names for the stars in the 2MASS database due to
differences in rounding the coordinates.
Note (2): The dereddening procedure is described in Paper I
(2003ApJ...599.1082M 2003ApJ...599.1082M).
Note (3): A Local Standard of Rest rotation velocity of 220km/s and a solar
peculiar velocity of (u, v, w)=(-9, 12, 7)km/s are adopted.
