RAVE DR6 catalog of [O/Fe] ratios in dwarf and turn-off stars (ravedr6_contrib.ratio_ofe_dwarfs)
The table has 8017 rows, 7 columns.
Description
This catalog contains [O/Fe] ratios computed in 1D LTE and <3D> NLTE thanks to spectral fitting of the oxygen triplet at 8446A, in 8817 dwarf and turn-off stars. Published in A&A DOI (https://doi.org/10.1051/0004-6361/202453526)
Changes: 30.06.2025 Chi^2 values for both o_fe_1d_lte and o_fe_3d_nlte columns were added in this new version
