SDSS-V The APOGEE Northern and Southern Spectrographs APOGEE-1 and APOGEE-2 constituted a high-resolution, near-infrared spectroscopic survey of several hundred thousand stars in the Milky Way Galaxy. Spectra are observed with custom-built, multi-object spectrographs, which record the spectra of 300 targets simultaneously across the H-band wavelength regime with an approximate resolution of 22,500. The APOGEE spectrographs […]
