A Catalog of Stellar Abundances for DESI Early Data Release
Meng Zhang ; Maosheng Xiang
A catalog of atmospheric parameters and elemental abundances for about 520,228 stars in the early data release of the DESI spectroscopic survey. The catalog content includes stellar basic atmospheric parameters (Teff, logg, vmic) and abundances for 12 elements (C, N, O, Mg, Al, Si, Ca, Ti, Cr, Mn, Fe, Ni) derived with the DD-Payne method, along with extinction, distance, and orbital parameters further inferred based on the atmospheric parameters and multi-band photometry. Internal precision of the label estimates are about 20K for Teff, 0.05dex for logg, and 0.05dex for most elemental abundances. Distance of the sample stars spread out to 100 kpc. The catalog is in .FITS format. Size of the catalog: 233MB.
