Data Reduction Pipelines SDSS spectra are generated by running raw data from the SDSS Observatories in the North and South through a series of data reductions, orchestrated by SDSS Pipelines. The following table lists each SDSS Data Reduction Pipeline (DRP), indicating whether it is current in SDSS-V or completed in a previous phase of SDSS: […]

Science Programs
Summary of BHM Time-Domain Spectral Programs The BHM optical (BOSS) repeat spectral time-domain programs emphasize the astrophysics of quasars, including studies of BH masses, binarity, accretion and events, broad line region (BLR) dynamics, outflows, etc., requiring spectral sampling at a broad range of timescales/cadence, ranging from days to decades; this is achieved via several tiers. […]
SPIDERS
‘SPectroscopic IDentfication of ERosita Sources’ Summary The SDSS-V SPIDERS project aims to characterize a large sample of X-ray sources through an ambitious program of optical spectroscopic follow up. The SPIDERS project has two main science themes – the follow up of X-ray point-like sources (‘SPIDERS-AGN’), and the follow up of X-ray/optical cluster candidates ( ‘SPIDERS-Clusters’). […]
Reverberation Mapping
Summary The SDSS-V/BHM Reverberation Mapping (RM) project seeks to measure the time lag of broad emission line response to continuum variability, and hence virial BH mass estimates, aiming for a large and uniformly selected sample of quasars across a wide range of luminosities and redshifts. The target sample is overall a flux-limited one without other […]
Tutorials Overview
Welcome to the SDSS tutorial section. This section contains a series of hands-on tutorials to learn how to work with different aspects of the SDSS data. If you are unsure what kind of SDSS data or which SDSS survey is best for your science, then go the the mapper overview page: this page contains short […]
Data Volume for DR18
SDSS Science Archive Server (SAS) The SAS is a hierarchical directory structure with named data products, and can be navigated directly: Individual data products are either replacements from previous data releases, and add incrementally to the data volume, or contain links to previous data releases, and add cumulatively to the data volume. Whether you are […]
Bulk Data Downloads
All data can be downloaded directly from data.sdss.org and dr18.sdss.org using the rsync or wget commands. Access is also available via Globus Online. The Data Model page has a description of the directory structure and file formats. Note that the total SDSS data volume is > 650 TB; see the data volume table including all data releases. If you need a substantial fraction of […]
Education and Public Outreach
The Sloan Digital Sky Survey is committed to working towards making the science and engineering results of our surveys accessible to the public. We are also enthusiastic about supporting the use of SDSS data for training and education. We aim to do this through informal and formal education, citizen science, news, and social media. A […]
Publications
This page lists peer-reviewed publications from the SDSS team. The publications in this list are divided among the phases of the SDSS. Within each phase, publications are listed by SDSS component survey. Click the links to view the publications. SDSS-V SDSS-IV SDSS-III SDSS-I/-II For publications from the first two phases of the Sloan Digital Sky […]
Science Results
The Sloan Digital Sky Survey has been working for more than 20 years to make a map of the Universe, and will continue for many years to come. The video below shows a flythrough of the SDSS’s map of the large-scale structure of the Universe. But this map in itself is not the SDSS’s real […]
