Spitzer UKIDSS Ultra Deep Survey (SpUDS)
IRSA is currently serving the final data release (DR2) of the Spitzer Public Legacy Survey of the UKIDSS Ultra Deep Survey (SpUDS), a Cycle 4 Spitzer Legacy program. This project 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).
DR2 consists of four-band IRAC mosaics, coverage maps, uncertainty and standard deviation images and MIPS 24 micron mosaics and uncertainty images at the original and subsampled pixel scales. IRAC and MIPS catalogs are available through IRSA's Catalog Search service.
You can get a close-up map of a region by clicking on the above image, or by typing a coordinate below.
Use the form below to enter a coordinate or object name to search for data, or click the image above to retrieve cutout images for your area of interest (along with links to the original mosaics). You can also bypass searching and browse the images.
Also available are SpUDS image "cutouts" using IRSA's Cutouts Service, which is a general tool to create single or multiple small FITS (and JPEG) image cutouts of data sets archived at IRSA.
