VizieR Online Data Catalog: K2 asteroseismic KEYSTONE Sample. I. (Lund+, 2024)

There are three datasets in total providing information on atmospheric, astrometric, and asteroseismic properties. In all tables each star is identified by its K2 EPIC ID. Additional identifiers (HIP, GAIA) are provided in the table containing astrometric information. The table with atmospheric parameters provide measurements of T_eff, [Fe/H], log(g), vsin(i), and radial velocity from a spectroscopic analysis. Additionally, T_eff and theta (angular diameter) is provided from the infrared flux method (IRFM). The table with astrometric parameters provide information on reddening, distances, and luminosities. The asteroseismic properties table provide measurements of the global asteroseismic parameters Δν and ν_max from three different analysis pipelines. Where relevant, uncertainties defined either as a symmetric error (e_) or as upper (E_{) and lower (e}) uncertainties. The atmospheric and astrometric tables include relevant notes on the individual stars providing information on, e.g., binarity, know exoplanets, and sources to the literature.
