Spitzer Archival Far-Infrared Extragalactic Survey (SAFIRES)

The Spitzer Archival FIR Extragalactic Survey (SAFIRES) is an offshoot of the Spitzer Space Telescope Enhanced Imaging Products (SEIP). SAFIRES applies the SEIP project's methods to the remaining two MIPS bands, located at far-infrared wavelengths of 70 and 160 microns. Due to the complexity of far-infrared observations, these bands require an expansion of SEIP's standard pipeline through the addition of reprocessing tools. These additional steps are required to remove obvious artifacts before extracting useful measurements. As a result, these bands were not included in the SEIP project, but were later funded through an additional NASA Astrophysics Data Analysis Program (ADAP) grant. To ensure high reliability, the SAFIRES sample includes no fields near the Galactic disk; these observations comprised more than half of the area observed by Spitzer, but the practical drawbacks of Galactic contamination would inhibit the ability to maintain the level of reliability desired in the SAFIRES products. As with SEIP, the SAFIRES source lists contains no extended sources. The remaining sample comprises nearly 1132 fields spanning almost 180 square degrees of sky.

斯皮策存档远红外河外巡天（Spitzer Archival FIR Extragalactic Survey, SAFIRES）是斯皮策空间望远镜增强成像产品（Spitzer Space Telescope Enhanced Imaging Products, SEIP）的衍生项目。SAFIRES将SEIP项目的处理方法应用于剩余的两个MIPS波段，这些波段对应70微米与160微米的远红外（far-infrared）波长。由于远红外观测的复杂性，需对SEIP的标准处理流程进行扩展，新增再处理工具。这些新增步骤需在提取有效测量数据前，移除明显的伪影（artifacts）。因此，这些波段最初未被纳入SEIP项目，后续则通过美国国家航空航天局（National Aeronautics and Space Administration, NASA）追加的天体物理学数据分析计划（Astrophysics Data Analysis Program, ADAP）拨款获得了资助。为保障高可靠性，SAFIRES样本未包含银盘（Galactic disk）附近的天区——尽管此类观测覆盖了斯皮策望远镜观测总天区的一半以上，但银河污染带来的实际弊端，将妨碍SAFIRES产物达到预期的可靠性水准。与SEIP一致，SAFIRES的源表（source lists）不含延展源（extended sources）。剩余样本涵盖近1132个观测场，覆盖约180平方度的天区。
