Heavy Element Abundances of Heavy-Element Enhanced Stars from the Four-hundred Very Metal-Poor Stars Studied with LAMOST and Subaru

This dataset accompanies the paper "Four-hundred Very Metal-poor Stars Studied with LAMOST and Subaru. IV. Heavy Elements Enhanced Stars". It includes three main files: Atmospheric_Parameters.txt, which contains the adopted atmospheric parameters of the sample stars; Element_Abundances.txt, which provides the heavy element abundances; and Line_list.csv, which details the atomic line list utilized in this study. The sample is derived from the LAMOST/Subaru joint project. For detailed descriptions of target selection and observations, please refer to Paper I (DOI: 10.3847/1538-4357/ac6515). The chemical abundance analysis is detailed in Paper II (DOI: 10.3847/1538-4357/ac6514), and the clustering and chemodynamical analysis can be found in Paper III (DOI: 10.3847/1538-4357/ad31a6).
