摘要：

我们目前斯皮策70和160微米的观测COSMOS斯皮策调查（S-COSMOS）。讨论了由图像和源目录组成的公开发布产品的数据处理技术。我们提出了准确的70和160微米的COSMOS领域的源计数，并找到合理的协议与其他领域的测量和模型预测。先前报告的GOODS-North和河外第一眼巡天的计数用最新的校准进行了更新，并根据大面积SWIRE巡天测量了计数，以限制亮源计数。基于深S-COSMOS数据，我们测量了MIPS 160微米波段的河外混淆噪声水平sigma_c = 9.4+/-3.3 mJy（q=5），并报告了MIPS 70微米波段的最新混淆噪声水平sigma_c = 0.35+/-0.15 mJy（q=5）。

英文摘要：

We present Spitzer 70 and 160 micron 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 micron 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 sigma_c = 9.4+/-3.3 mJy (q=5) for the MIPS 160-micron band based on the deep S-COSMOS data and report an updated confusion noise level of sigma_c = 0.35+/-0.15 mJy (q=5) for the MIPS 70-micron band.
