SDSS Mirror Site Resource Page

This site is intended to support people wishing to create a SDSS Catalog Archive Server mirror site.

SDSS DR15 catalog data is now available for download - the BestDR15 database can be downloaded as a multi-file SQL Server backup. It is about 6.5 TB in size (compressed) and the uncompressed size of the database is 12+ TB. Please contact SDSS Help Desk for further information.
