S-CANDELS Spitzer Data
The Spitzer-Cosmic Assembly Deep Near-Infrared Extragalactic Legacy Survey (S-CANDELS) is a Spitzer Cycle 8 Exploration Program (PI G. Fazio) that obtained deep IRAC channel 1 and 2 imaging in five widely separated extragalactic fields: the UKIDSS Ultra-Deep Survey (UDS), the Extended Chandra Deep Field South (ECDFS), COSMOS, the HST Deep Field North (HDFN), and the Extended Groth Strip (EGS). S-CANDELS builds upon the existing coverage of these fields obtained as part of the Spitzer Extended Deep Survey (SEDS), a Cycle 6 Exploration Program, by increasing the integration time from 12 hours to a total of 50 hours within a smaller area of 0.16 deg2.
COSMOS (0.3 by 0.45 deg) ECDFS (0.38 by 0.43 deg) EGS (0.58 by 0.12 deg)
HDFN (0.31 by 0.29 deg) UDS (0.46 by 0.24 deg)
