MaNGA Data

MaNGA intermediate and final data products are stored on the SDSS Science Archive Server (SAS).

The end-stage MaNGA data product is a 3-D data cube, with two spatial dimensions and one spectral dimension. A data cube contains sky-subtracted, spectrophotometrically calibrated spectra from all individual dithered observations through the MaNGA bundle, combined onto a regular 0.5 arcsecond grid.

Individual MaNGA fiber spectra (sky-subtracted and spectrophotometrically calibrated) are also provided in summary row-stacked format for each galaxy. For each galaxy observed there are between 57 and 1905 of these row stacked spectra (RSS), one row per fiber, per exposure.

Raw MaNGA data are recorded by the four BOSS cameras as 2-D images. These are extracted into 1423 one-dimensional spectra (one for each MaNGA fiber) and processed through the Data Reduction Pipeline (DRP) up to and including flux calibration, after which the spectra are collated into Row Stacked Spectra (RSS) and assembled into 3-D Data Cube formats.

MaNGA summary catalogs are served through the Catalog Archive Server (CAS).
