Description:
Spectrum synthesis calculations were performed on four different families of model atmospheres: 3D hydrodynamic model atmospheres from the STAGGER-grid (Magic et al. 2013A&A...557A..26M, Cat. J/A+A/557/A26); 1D model atmospheres determined by averaging the <3D> STAGGER model atmospheres (henceforth <3D> model atmospheres; Magic et al. 2013A&A...560A...8M, Cat. J/A+A/560/A8); theoretical 1D hydrostatic model atmospheres from the ATMO-grid (the 1D equivalent of the STAGGER-grid, see Appendix A of Magic et al. 2013A&A...557A..26M, Cat. J/A+A/557/A26); and theoretical 1D hydrostatic model atmospheres from the MARCS-grid (Gustafsson et al. 2008A&A...486..951G). Table1 contains the line parameters that were adopted for the grids of abundance corrections. Table2 contains the 3D non-LTE versus 1D LTE abundance corrections for CI lines. Table3 contains the 3D non-LTE versus 1D LTE abundance corrections for OI lines. Table4 contains the 3D LTE versus 1D LTE abundance corrections for FeII lines. Table5 contains the 1D non-LTE versus 1D LTE abundance corrections for CI lines. Table6 contains the 1D non-LTE versus 1D LTE abundance corrections for OI lines. Table7 contains the stellar parameters and abundances for the 187 sample stars.
We here analyse a specific data-set: the extended GALAH dataset. This consists of stellar spectra from the GALAH survey (reduced as explained in Kos et al., 2017MNRAS.464.1259K), apparent magnitudes from a variety of photometric catalogues (AAVSO Photometric All Sky Survey - APASS; Henden et al. 2016, Cat. II/336, Gaia DR2; Gaia Collaboration et al. 2018, Cat. I/345. Two Micron All Sky Survey - 2MASS; Skrutskie et al. 2006, Cat. VII/233, Wide-field Infrared Survey Explorer - WISE; Wright et al. 2010, Cat. II/311), and the parallax measurements from Gaia DR2. The data provided in this catalogue are described in Table A.1 of the paper.
