DR15 MaNGA Overview
MaNGA is the newest survey component of the Sloan Digital Sky Survey. Its goal is to map the detailed composition and kinematic structure of 10,000 nearby galaxies. MaNGA uses integral field unit (IFU) spectroscopy to measure spectra for hundreds of points within each galaxy. For a general introduction to MaNGA, see the MaNGA survey page on this site.

MaNGA Data
DR15 Scope and Status
DR15 includes data for 4,824 MaNGA data cubes (4,621 unique galaxies plus 67 repeat observations and 136 special ancillary targets from the Coma, IC342, and M31 ancillary programs).
The MaNGA data available in DR15 consist of the raw data from the first three years of the survey, the intermediate/final data reduction pipeline (DRP) products, and the first release of derived data products from the data analysis pipeline (DAP). These derived data products include maps of emission line fluxes, gas and stellar kinematics, and stellar population properties.
In addition, DR15 represents the first release of the MaStar stellar library consisting of reduced stellar spectra observed using the MaNGA IFU fiber bundles during the APOGEE-2 bright-time observing program. See the Data Access section below for more information.
Finally, DR15 contains new MaNGA Value Added Catalogs, these can be found here.
Future Data
DR15 is the third spectroscopic data release for MaNGA that includes a full release of DRP, DAP, and MaStar data products via both traditional methods and the Marvin interface. Future data releases will include more galaxies and MaStar stellar library objects that are currently being observed.
Data Access
MaNGA data can also be accessed using several SDSS interfaces.
Marvin
We are happy to announce the release of Marvin for DR15. Marvin is a new tool for accessing, visualizing, and analyzing MaNGA data on the web and on your computer. For more information see the Marvin page.
Science Archive Server (SAS)
MaNGA data cubes, row-stacked spectra, and the drpall summary table are available as FITS files through the Science Archive Server (SAS), which can return FITS spectra either individually or in bulk. For more information on retrieving MaNGA data from the SAS, see the MaNGA Data Access page for details.
CasJobs
You can search for MaNGA data within the drpall summary table more flexibly with the CasJobs data access tool. With CasJobs, you can submit large queries that run for up to 8 hours and can return millions of objects. You can save results into a personal MyDB database for later analysis.
MaNGA data are part of the DR15 context - don't forget to change to the DR15 context when you want to find MaNGA data. MaNGA summary data are in the mangaDrpAll table, and targeting data are available in the mangatarget table.
SkyServer
Information for individual MaNGA targets are now shown in the SkyServer Explore tool, such as for this sample MaNGA target galaxy. The SkyServer site includes direct links to the MaNGA data cubes stored on the SAS.
You can search for MaNGA data using Structured Query Language (SQL) with the SkyServer SQL Search tool. MaNGA summary data are in the mangaDrpAll table, and targeting data are available in the mangatarget table.
