VizieR Online Data Catalog: High-precision abundance of the Helmi streams (Matsuno+, 2022)
Abstract
We tabulate measured equivalent widths and their uncertainties together with information on the lines, such as wavelength, excitation potential, and log(gf)-values. We also include line-by-line abundances, for which we also provide uncertainties due to stellar parameters and equivalent widths. The weights used to compute the best estimate of the abundance of each species is also included. These data can be used to reproduce all the figures and the abundance table.
