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:
- The very first set of spectra and data products from the Milky Way Mapper (MWM) science programs, and a significant update of spectra and data products from the Black Hole Mapper (BHM) science programs
- A preview from Local Volume Mapper, in the shape of a Helix Nebula tile
- Targeting catalogs prepared for the BHM and MWM science programs, as well as for the open fiber programs
- Several Value Added Catalogs (VACs), prepared by the BHM and MWM science teams
- Brand-new user interfaces, Zora and Valis, to interact with SDSS-V spectra and data products, in a web browser or API
- Several Python Notebooks tutorials that also run in SciServer Compute, to showcase what you can do with SDSS data products
Access to the DR19 data products is described on this page, while the Black Hole Mapper, Milky Way Mapper, and Local Volume Mapper data pages offer more detailed descriptions of the data products, as well as caveats.
