Data associated with the publication: Coadded Spectroscopic Stellar Parameters and Abundances from the LAMOST Low Resolution Survey

I combine duplicate spectroscopic stellar parameter estimates in the LAMOST Data Release 6 Low Resolution Spectral Survey A, F, G, and K Type stellar parameter catalog. The process of combining multiple sets of spectroscopic stellar parameter estimates typically reduces the uncertainty on the estimates by a factor of two. Moreover, this trivializes the process of performing coordinate-based cross-matching with other catalogs. Similarly, I combine duplicate stellar abundance estimates for the Xiang et al. (2019) catalog which was produced using LAMOST Data Release 5 Low Resolution Spectral Survey data. These data have numerous applications in stellar, galactic, and exoplanet astronomy.
