Far-Infrared Deep Extragalactic Legacy Survey (FIDEL)

Far-Infrared Deep Extragalactic Legacy Survey (FIDEL) contains sensitive and extensive far-infrared deep field observations with Spitzer to detect warm dust emission from hundreds of relatively ordinary starburst galaxies and active galactic nuclei at redshifts of 1 to 2 (7 to 10 billion years ago), and thousands more nearby. The survey also detected tens of thousands of high redshift objects at mid-infrared wavelengths. The program obtained data in three fields on the sky. The bulk of the data is in two fields, the Extended Chandra Deep Field South (ECDFS) and the Extended Groth Strip (EGS). A smaller amount of additional data was obtained in the GOODS-North area.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

远红外深空河外遗产巡天（Far-Infrared Deep Extragalactic Legacy Survey, FIDEL）包含利用斯皮策望远镜（Spitzer）开展的灵敏且广泛的远红外深空观测，旨在探测红移1至2（即70至100亿年前）的数百个相对普通的星暴星系与活动星系核的暖尘埃发射，以及数千个更近的此类天体。该巡天还在中红外波段探测到数万个高红移天体。该项目在天空中的三个天区获取了数据：大部分数据来自扩展钱德拉南天深空场（Extended Chandra Deep Field South, ECDFS）和扩展格罗思带（Extended Groth Strip, EGS）两个天区，少量补充数据则来自 GOODS-North 区域。

该数据集或服务由 IPAC 的红外科学档案库（Infrared Science Archive, IRSA）提供。IPAC 由加州理工学院根据与美国国家航空航天局（National Aeronautics and Space Administration, NASA）签订的合同运营。
