SIMPLE Spitzer and Ancillary Data
IRSA is currently serving the first data release (DR1) of the Spitzer IRAC/MUSYC Public Legacy Survey in the Extended Chandra Deep Field South (SIMPLE), a Cycle 2 Spitzer Legacy program. SIMPLE consists of deep IRAC observations (several hours per pointing) covering the 0.5 x 0.5 deg area surrounding the GOODS CDF-South. This low-background region of the sky has by far the best supporting data of any cosmological survey field of comparable area, with deep observations from the X-rays to the thermal infrared.
The first delivery (DR1) of the Spitzer data from the SIMPLE Legacy Program are available here using spatial and visualization tools.
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). SIMPLE catalog data are available using IRSA's Catalog Search Engine, which allows for complex search queries. You can also bypass searching and browse the images or catalog.
Also available are SIMPLE 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.
Access all the Spitzer Legacy datasets at IRSA.
