VizieR Online Data Catalog: Stars in the Sagittarius stream (Vasiliev+, 2021)
Abstract
To study the kinematics of the Sgr debris, we concentrate on the red giant branch (RGB) population. These are the brightest stream members and therefore have the lowest proper motion uncertainty. We start by cross-matching the Gaia DR2 source catalogue with the 2MASS catalogue (Skrutskie et al. 2006AJ....131.1163S, Cat. VII/233). Only objects with Galactic latitude |b|>5°, extinction-corrected 13<G<18,BP-RP>1 and parallax {varpi}<0.1mas as reported by Gaia were included in the cross-match.
We provide the catalogue of ~55000 high-probability stream members described in Section 2, which combines the positions and proper motions from Gaia, distances estimated from Gaia RR Lyrae stars, and for a small subset of stars (~4500) - line-of-sight velocities from various spectroscopic surveys.
