The Great Observatories Origins Deep Survey (GOODS) aims to unite extremely deep observations from NASA's Great Observatories (Spitzer, Hubble and Chandra), ESA's Herschel and XMM-Newton, and the most powerful ground-based facilities. The aim is to survey the distant universe to the faintest flux limits across the broadest range of wavelengths.
The Multiwavelength Survey by Yale-Chile (MUSYC) consists of deep optical medium-band and broadband optical and near-IR imaging of the ~30'x30' Extended Chandra Deep Field South. This field includes the GOODS-South field and the Hubble Ultra Deep Field, and covers the same area as the SIMPLE Spitzer Legacy program.
