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 […]
DR18 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 […]
BOSS Spectrographs
The two identical BOSS spectrographs were rebuilt from the original SDSS spectrographs. Each spectrograph has two cameras, one red and one blue, with a dichroic splitting the light at roughly 6000 Angstroms. The BOSS spectrographs were custom designed for BOSS, an SDSS-III spectroscopic survey that measured redshifts of 1.5 million luminous red galaxies and Lyman-alpha […]
APOGEE Spectrographs
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 are […]
Mappers
SDSS-V is an all-sky, multi-epoch spectroscopic survey that will yield optical and IR spectra of over 8 million objects and IFU spectra of over 4,300 square degrees on the sky during its seven year lifetime (2020-2027). Using SDSS’s facilities at Apache Point and Las Campanas Observatories, SDSS-V will survey the entire sky — mapping the […]
DR18 Glossary of SDSS Terminology
This Glossary is a work in progress, and more terms will be added during the lifetime of SDSS-V. If you have come across SDSS Terminology that is not explained yet in the Glossary below, then please let us know via the SDSS Helpdesk at helpdesk@sdss.org. ABCDEFGHIJKLMNOPQRSTUVWXYZ A Adaptive Moment A method of measuring object shapes […]
DR18 BHM Overview
Black Hole Mapper (BHM) emphasizes the study of quasars/AGN, as among Universe’s most luminous objects, powered by accretion onto supermassive black holes (SMBHs), and co-evolving via feedback with the host galaxies in which they reside. BHM exploits – with order(s) of magnitude advances – two hallmark characteristics of quasars: their marked variability on a range […]
