Downloading and caching Galaxy- and Group-galaxy catalogues

This section of the documentation describes how to get up and running with the galaxy and group-galaxy catalogues provided by SDSS_Catl_Utils. To see if SDSS_Catl_Utils provides the catalogues that you need, check Calderon et al. (2018).

SDSS_Catl_Utils provides a handful of homogeneously processed galaxy and group galaxy catalogues and associated group membership data. These catalogues have been prepared into a standard form, and so once they are downloaded they will be directly added to your cache and can immediately be used for your science applications.

The class responsible for downloading and caching these catalogues is DownloadManager.
