Abstract:
The 2022ApJS..259...35A 2022ApJS..259...35A paper documents the seventeenth data release
(DR17) from the Sloan Digital Sky Surveys; the fifth and final release
from the fourth phase (SDSS-IV). DR17 contains the complete release of
the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA)
survey, which reached its goal of surveying over 10,000 nearby
galaxies. DR17 also contains the complete release of the Apache Point
Observatory Galactic Evolution Experiment 2 (APOGEE 2) survey that
publicly releases infrared spectra of over 650,000 stars. The main
sample from the Extended Baryon Oscillation Spectroscopic Survey
(eBOSS), as well as the subsurvey Time Domain Spectroscopic Survey
data were fully released in DR16. New single-fiber optical
spectroscopy released in DR17 is from the SPectroscipic IDentification
of ERosita Survey subsurvey and the eBOSS-RM program. Along with the
primary data sets, DR17 includes 25 new or updated value-added
catalogs. This paper concludes the release of SDSS-IV survey data.
SDSS continues into its fifth phase with observations already underway
for the Milky Way Mapper, Local Volume Mapper, and Black Hole Mapper
surveys.
Description:
DR17 constitutes the sixth release of data from APOGEE, which has run
in two phases (APOGEE-1 and APOGEE-2) spanning both SDSS-III and
SDSS-IV. As part of SDSS-III, the APOGEE-1 survey operated for
approximately 3yr from 2011 August to 2014 July using the 2.5m Sloan
Foundation Telescope at APO. At the start of of SDSS-IV, APOGEE-2
continued its operations in the northern hemisphere by initiating a
∼6yr survey (APOGEE-2N). Thanks to unanticipated on-sky efficiency,
APOGEE-2N operations concluded in 2020 November with an effective
∼7.5yr of bright-time observations, with many programs expanded from
their original 6yr baseline. In 2017 April, operations began with the
newly built APOGEE-S spectrograph and associated fiber plugplate
infrastructure on the 2.5m Irenee du Pont Telescope at LCO; APOGEE-2S
observations concluded in 2021 January.
Compared to the previous APOGEE data release (DR16), DR17 contains
roughly two additional years of observations in both hemispheres.
The final APOGEE survey map is shown in Figures 2 and 3.
See Section 4 for further explanations.
DR17 is the final release of data from APOGEE-2 and includes all data
from the SDSS-III/APOGEE and SDSS-IV/APOGEE-2 surveys. The observation
cutoff date for APOGEE-2N is November 07, 2020 (MJD 59160) and for
APOGEE-2S is January 20, 2021 (MJD 59234).
