VizieR Online Data Catalog: Titans metal-poor reference stars. I. (Giribaldi+, 2021)
Abstract
The main source of sample stars was the work of Casagrande et al. (2010A&A...512A..54C, Cat. J/A+A/512/A54). Additional candidates were assembled from Ryan et al. (1996ApJ...471..254R); Gehren et al. (2006A&A...451.1065G); Reddy & Lambert (2008MNRAS.391...95R); Nissen & Schuster (2010A&A...511L..10N, Cat. J/A+A/511/L10); Beers et al. (2017ApJ...835...81B, Cat. J/ApJ/835/81).
Table 2 displays the fundamental parameters, metallicities, V magnitudes, and reddening of the Titans. Uncertainties accompanying the temperature values are internal. To compute total uncertainties, the estimated model accuracy error of +/-50K must be included in the error expansion as discussed in Sec. 3.4 in the paper. The bottom part of the table incorporates seven Gaia benchmark stars. Table 4 displays the membership classification of the Titans to the Galactic substructures. Parallax values are from Gaia EDR3. In the membership column GE means Gaia-Enceladus, HS Helmi stream, and Sq Sequoia. The bottom part of the table incorporates seven Gaia benchmark stars. The symbol (+) means likely membership according to the criterion of Massari et al. (2019A&A...630L...4M) and (++) means according to the criterion of Myeong et al. (2019MNRAS.488.1235M).
