Abstract
This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17).

We would like to thank the Center for Cosmology and AstroParticle Physics (CCAPP) at the Ohio State University for their hospitality during "DocuBrew" 2019. This event held in 2019 August was the main venue for documentation updates for DR16 (including this paper), was organized by A.R., J.J., and A.-M.W and attended by R.B., J.B., B.C., K.D., S.H., A.J., J.H., K.M., J.R., J.S.-G., F.S., and M.T. (and remotely by H.J., J.B., J.H., J.S., C.G. J.C., S.A., R.T., B.L., and J.P.). Figures 1 and 2 were made by C.H. Figure 4 was made by A.R. and Figure 5 by M.V. and J.B. This research made use of astropy, a community-developed core python (http://www.python.org) package for Astronomy (Robitaille et al. 2013), ipython (Pérez & Granger 2007), matplotlib (Hunter 2007), numpy (Walt et al. 2011), scipy (Virtanen et al. 2020), and topcat (Taylor 2005). | ||||||||||||
