Spitzer Public Legacy Survey of the UKIDSS Ultra Deep Survey (SpUDS) is a survey of the ~1 square degree UKIDSS Ultra Deep Survey (UDS). The survey consists of deep IRAC and 24 micron MIPS observations. The UDS is the largest deep near-infrared (JHK) survey in existence, and the first capable of sampling representative cosmological volumes (100x100 Mpc) out to the highest redshifts (z>6).
