VizieR Online Data Catalog Extremely metal-poor stars CaII triplet (Carrera+, 2013)

The CaT calibration obtained in Paper I (Carrera et al., 2007AJ....134.1298C, Cat. J/AJ/134/1298) was obtained from observations of almost 500 RGB stars in 29 Galactic open and globular clusters, covering a total metallicity range of -2.33<=[Fe/H]<=+0.47. We used the same sample in this paper, so we refer the reader to Paper I for a detailed discussion about the observations and data reduction of these stars. (4 data files).
