This dataset provides radial velocities, $T_\text{eff}$, log $g$, [M/H] and [$\alpha$/M] with uncertainties for 870,518 refined M-type spectra from LAMOST DR10. The radial velocities have been updated using template matching and Doppler shift methods, combined with visual inspection to correct potential RV measurement errors in LAMOST. The stellar parameters and their uncertainties are derived from an ensemble of ten-fold cross-validated CNN models trained on LAMOST spectra with APOGEE labels.
