ADC_Keywords: Stars, giant ; Stars, M-type; Photometry, infrared ; Radial velocities Keywords: galaxies: individual (Sagittarius) - Galaxy: evolution - Galaxy: halo - Galaxy: structure - stars: kinematics - techniques: spectroscopic 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). 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.
