VizieR Online Data Catalog: Substructure in the stellar halo near the Sun. I. (Lovdal+, 2022)
Abstract
Overdensities in integrals-of-motion space of the Milky Way halo, corresponding to the statistically significant clusters presented in our paper. We provide the spatial location and extent of the extracted clusters, together with the halo star catalogue with corresponding cluster labels, corresponding to Table 1 and Table 2 of our paper.
In Table 1, the suffixes 0-2 correspond to the energy E, perpendicular momentum Lperp, and angular momentum in z-direction Lz. The quantities mu and sigma were computed using the original members of the cluster as assigned by the single linkage process, after scaling the features, so the indicated values correspond to values in the scaled data space. In Table 2, the spatial coordinates and velocity components correspond to a heliocentric cartesian coordinate system. (2 data files).- Publication:
