Spectroscopy of the Galactic bar. I.
Listed in IVOA Registry (Virtual Observatory)
We use Fabry-Perot absorption line imaging spectroscopy to measure radial velocities using the CaII line in 3360 stars toward three lines of sight in the Milky Way's bar: Baade's Window and offset position at (l,b)~(+/-5.0,-3.5{deg}).
Description
This sample includes 2488 bar red clump giants, 339 bar M/K-giants, and 318 disk main-sequence stars. We measure the first four moments of the stellar velocity distribution of the red clump giants, and find it to be symmetric and flat-topped.
We also measure the line-of-sight average velocity and dispersion of the red clump giants as a function of distance in the bar.
