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.
SEGUE Duplicate Observations Catalog
List of identifiers for repeat SEGUE observations.
This catalog provides a list of identifiers for repeat spectroscopic observations of individual photometric targets in SEGUE. These are particularly useful for testing consistency of the SEGUE Stellar Parameters Pipeline (SSPP).
