Galactic H II Regions in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Based on LAMOST Medium-Resolution Spectroscopic Survey of Nebulae (MRS-N) data and the Wide-field Infrared Survey Explorer Galactic H II region catalog, we construct a sample of 280 Galactic H II regions and candidates in the outer Galaxy (80° ≲ l ≲ 220°). Using MRS-N optical spectra, we measure four emission lines (Hα...
