The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar, and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from Sloan Digital Sky Surveys; fifth and final fourth phase (SDSS-IV). DR17 contains complete of Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal surveying over 10,000 nearby galaxies. The MaNGA Stellar Library (MaStar) accompanies this data, providing observations almost 30,000 stars through instrument during bright time. also Galactic Evolution Experiment 2 (APOGEE-2) survey publicly releases infra-red spectra 650,000 stars. main sample Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well sub-survey Time Domain (TDSS) were fully released in DR16. New single-fiber optical spectroscopy is SPectroscipic IDentification ERosita (SPIDERS) eBOSS-RM program. Along with primary sets, includes 25 new or updated Value Added Catalogs (VACs). concludes SDSS-IV data. SDSS continues into already underway for Milky Way Mapper (MWM), Local Volume (LVM) Black Hole (BHM) surveys.
