In addition to the primary SDSS photometry and spectroscopy, there are a few extra catalogs created by our collaborators that are distributed through the SAS. These Value-Added Catalogs (VACs) are listed below, and include catalogs that were released in earlier data releases.
GEMA-VAC: Galaxy Environment for MaNGA Value Added Catalog
Catalog of environment characterisations for the MaNGA DR17 sample.
The environment in which a galaxy resides plays an important role in its formation and evolution. Galaxies suffer intrinsic and secular evolution processes (i.e. nature processes), but they are also exposed to the influences of their local and large-scale environments (i.e. nurture processes). This value added catalog contains several quantifications of the environment for MaNGA galaxies, based on the methods described in Argudo-Fernández et al. (2015), as well as Etherington & Thomas (2015) and Wang et al. (2016). The DR17 GEMA-VAC catalog will be described in more detail in Argudo-Fernádez et al. (in prep.). This VAC is also available through Marvin. We recommend that you always use the latest updated catalog (DR17). The DR15 version of the GEMA VAC is still available here.
