We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82.

By making use of all available data in the SDSS archive, our co-added images are optimized for depth. Input single-epoch frames were properly processed and weighted based on seeing, sky transparency, and background noise before co-addition. The resultant...[Show more]
