Extended Data Table 3 Spectroscopic parameters and one-dimensional LTE chemical abundances for the Gemini–GRACES spectra

From: A stellar stream remnant of a globular cluster below the metallicity floor

  1. The uncertainties of Fe i measurements correspond to the line-to-line scatter in the Fe i abundances only, whereas uncertainties on [Fe ii/H] and [X/Fe] combine the measurement uncertainties (as σ/\(\sqrt{N}\)) and the uncertainties due to the stellar parameters, added in quadrature. NLTE corrections are listed in Extended Data Table 2; the averaged NLTE corrections are applied here, other than for Na i, for which individual line calculations per star were applied. We adopt the metallicities for these stars from [Fe ii/H].
