The Catalog and procedures for " Model-Driven Stellar Spectroscopy with the Total Differential Spectra Model (TDSM): Framework and Its Application to 11 Million LAMOST Low-Resolution Spectra"

This FITS file contains a catalog of stellar atmospheric parameters derived from LAMOST Data Release 10 (DR10) low-resolution spectra using the TDSM pipeline, a physically motivated neural network architecture that self-consistently emulates both the flux and its first-order derivative of the ab initio stellar spectra. The catalog covers the parameter range of 3000<T_eff<45,000 K, -1<log g<5, and -4.0<[Fe/H]<0.5, and provides eight stellar labels: T_eff, log g, [Fe/H], [$\alpha$/Fe], [C/Fe], [N/Fe], [Mg/Fe], and v_mic.

The catalog contains basic information from the LAMOST pipeline, including SPECID, RA, DEC, SNR_G, SNR_I, FILENAME, UNIQFLAG, and STAR_ID, together with the stellar parameters derived by TDSM and their uncertainties. For parameters with calibration, both the calibrated values and the corresponding pre-calibration results (*_RAW) are provided. The catalog also includes CHI2 and CORR and quality flags (CHI2_FLAG, FLAG_EW_CA_H, FLAG_EW_CA_K, FLAG_EW_H_ALPHA, and FLAG_EW_H_BETA).
