Description
We present Spitzer 70 and 160 μm observations of the COSMOS Spitzer
survey (S-COSMOS). The data processing techniques are discussed for the
publicly released products consisting of images and source catalogs. We
present accurate 70 and 160 μm source counts of the COSMOS field and
find reasonable agreement with measurements in other fields and with
model predictions. The previously reported counts for GOODS-North and
the extragalactic First Look Survey are updated with the latest
calibration, and counts are measured based on the large area SWIRE
survey to constrain the bright source counts. We measure an
extragalactic confusion noise level of σ c = 9.4
± 3.3 mJy (q = 5) for the MIPS 160 μm band based on the deep
S-COSMOS data and report an updated confusion noise level of
σ c = 0.35 ± 0.15 mJy (q = 5) for the MIPS 70
μm band.
