Available Paths

Paths are defined for each public data release, any internal SDSS releases, as well as for “working” paths not included in any data release. The available paths for each release are shown below. To learn how to add a new path, see Add Paths into the Tree and follow the instructions.

Current Working Paths

  • sdsswork - the latest “working” path definitions

  • sdss5 - temporary working paths for SDSS-V

Latest Path Evolution

sdss_access paths sometimes change between various SDSS data releases. Here we show changes for the latest public data release. See the complete path evolution for a full list of changes over all releases.
