The SDSS imaging camera took its first science quality data the night of September 19, 1998, and was the world’s most productive wide-field imaging facility until its last night of science quality data on November 18, 2009. In between it took a total of around 35,000 square degrees of images, covering a unique footprint of […]

Completed Spectroscopic Surveys
The Sloan Digital Sky Survey started routine observing in 2000, and since then has completed through four generations of surveys. The current generation is the Fifth Generation of Sloan Digital Sky Surveys (SDSS-V), and the data of its mapper programs can be found in Data Release 19. The following is a list of all the […]
Tutorials
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 Release 19
DR19 is the second data release for the fifth phase of the Sloan Digital Sky Survey (SDSS-V). Its content is described in detail on the DR19 data release paper. DR19 includes the following: Access to the DR19 data products is described on this page, while the Black Hole Mapper, Milky Way Mapper, and Local Volume […]
BHM Caveats
On this page we document a number of known issues with the BOSS data released in SDSS DR19 Targeting Caveats Missing MOS Target Cartons and Semaphore Flag Descriptions In DR19, there are some cartons included in the semaphore SDSS-V Targeting Flags definitions that are not included in the mos_target product or the tables loaded into […]
Reverberation Mapping
Summary The SDSS-V/BHM Reverberation Mapping (RM) project seeks to measure the time lag between variability signals in the quasar continuum and the response/echo from the broad emission lines, and hence make virial black hole (BH) mass estimates; aiming for a large and uniformly selected sample of quasars across a wide range of luminosities and redshifts. […]
SPIDERS
SPectroscopic IDentfication of ERosita Sources Summary The SDSS-V/BHM SPectroscopic IDentfication of ERosita Sources (SPIDERS) project aims to characterize a large sample of X-ray sources through an ambitious program of optical spectroscopic follow up. SPIDERS 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 […]
BHM Targeting Cartons
This page provides a complete list of all BHM-led science target cartons that have been considered within SDSS-V, up to and including the DR19 data release. These BHM cartons can be grouped by a ‘targeting generation’ identifier. A targeting generation is simply a well-defined collection of versioned target cartons, which have been used at some […]
BHM Science Programs
The two main pillars of the Black Hole Mapper project are: i) time domain studies of quasars, and ii) large scale spectroscopic follow up of X-ray selected sources. This core is complemented by a small number of supplementary BHM programs, which increase the scientific grasp of the project. BHM Time-Domain Programs The BHM optical (BOSS) […]
MWM Targeting Cartons
This page is a comprehensive list of cartons available up through data release 19. Each carton is associated with a well defined targeting generation. These generations were used at different points in the survey for plate designs or Robostrategy designs for the FPS. For a full description of the targeting generations see the List of […]
