S-COSMOS Overview
S-COSMOS is a deep infrared imaging survey carried out with the Spitzer Space Telescope. The survey covers the entire 2 square degrees of the Cosmic Evolution Survey (COSMOS) field. The S-COSMOS and COSMOS projects are closely coupled; therefore, their data are served as one large COSMOS Archive using IRSA's general search service, Atlas. S-COSMOS is part of the Spitzer Legacy Program. The data products released are part of the Spitzer General Observer Cycle 2 (GO2) program, including predominantly IRAC products (images and catalog). MIPS data include shallow images/catalogs covering the entire COSMOS field. There are also deep MIPS images covering only a test field of 0.16 sq. degrees for the upcoming GO3 program. The GO3 products will become public in September 2008.
S-COSMOS MIPS 70um and 160um Photometry Catalog v3.0
Processing Details:
- Raw Data processed with GeRT, version 20060415
- RAW->BCDs: do(70/160)aor_cosmos_gert+caler+refilt.tsch
- BCDs coadd with MOPEX, version 16.3.7
- Catalogs based on PRF fitting from APEX tools within MOPEX
- MIPS calibration and color corrections from Gordon et al. 2007, PASP and Stansberry et al. 2007, PASP.
- Images and uncertainty images are in MJy/sr assuming a nu-Fnu = constant spectral-energy-distribution. Catalog flux densities are in mJy assuming same calibration and include a factor of 1.15 for emission outside of the measured PRF.
- Data Paper Reference: Frayer et al. 2009, AJ
