A Catalog of Distance Determinations for 7 Million Stars in LAMOST DR10
We present a catalog of distances for the entire LAMOST DR10 low-resolution catalog version 2.0, encompassing approximately 7 million AFGK-type spectra. A comparison with Gaia parallaxes shows good consistency across the data. For parallaxes below 1 mas, the estimated distances are underestimated by 4% for the K band and 10% for the G band, while for parallaxes below 0.25 mas, the distances are overestimated by 9% for the K band and 7% for the G band. Distance uncertainties initially increase with distance, with relative distance uncertainties starting at 5% at 1 kpc and rising to 17% at 20 kpc, then decreasing to 10%–15% for distances greater than 50 kpc.
