FPI+ was the standard tracking camera for the SOFIA telescope with a 1024x1024 pixel science grade CCD sensor. As a science instrument it was intended to be used as a fast frame-rate imaging photometer in the 360 - 1100 nm wavelength range. The FPI+ CCD had a plate scale of 0.51 arcsec/pixel and a square field of view of 8.7x8.7 arcminutes. Its permanent installation on the SOFIA telescope allowed for its use while any other science instrument was installed on the main Science Instrument flange. Five Sloan Digital Sky Survey filters u', g', r', i', z' and a Schott RG1000 NIR cut on filter were available.
HAWC+ was a far-infrared camera and imaging polarimeter. It was designed to allow total and polarized flux imaging in five broad bands between wavelengths of 50 um and 240 um. Diffraction-limited imaging yielded spatial resolutions of ~5 - 20 arcseconds with fields of view ~2 - 10 arcminutes, respectively.
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.

Description:
The Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (S-CANDELS) is a Spitzer Cycle 8 Exploration Program (PI G. Fazio) that obtained deep IRAC channel 1 and 2 imaging in five widely separated extragalactic fields: the UKIDSS Ultra-Deep Survey (UDS), the Extended Chandra Deep Field South (ECDFS), COSMOS, the HST Deep Field North (HDFN), and the Extended Groth Strip (EGS). S-CANDELS builds upon the existing coverage of these fields obtained as part of the Spitzer Extended Deep Survey (SEDS), a Cycle 6 Exploration Program, by increasing the integration time from 12 hours to a total of 50 hours within a smaller area of 0.16 deg2.
The Spitzer Deep Wide-Field Survey is a four-epoch survey of roughly 10 square degrees of the NOAO Deep, Wide-Field Survey field in Boötes. The first visit to the field occurred very early in the Spitzer mission, in 2004 January, as part of the IRAC Shallow Survey (Eisenhardt et al. 2004). Subsequent visits to the field as part of the SDWFS program reimaged the same area to the same depth.
The Spitzer Science Center and IRSA have released a set of Enhanced Imaging Products (SEIP) from the Spitzer Heritage Archive. These include Super Mosaics (combining data from multiple programs where appropriate) and a Source List of photometry for compact sources. The primary requirement on the Source List is very high reliability -- with areal coverage, completeness, and limiting depth being secondary considerations. The SEIP include data from the four channels of IRAC (3.6, 4.5, 5.8, 8 microns) and the 24 micron channel of MIPS. The full set of products for the Spitzer cryogenic mission includes around 42 million sources.
SERVS is a warm Spitzer survey which images approximately 18 square degrees in the centers of the SWIRE XMM-LSS, ELAIS-S1, CDFS, Lockman and ELAIS-N1 fields to 20min (2mu Jy) depth at 3.6 and 4.5 microns. SERVS overlaps with the VISTA-VIDEO near infrared and Herschel-HERMES and SCUBA2-S2CLS far-infrared surveys.
The Spitzer/HETDEX Exploratory Large-Area (SHELA) survey covers ~24 sq. deg at 3.6 and 4.5 microns. The survey area falls within the footprints of the Sloan Digital Sky Survey "Stripe 82" region, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), and the Dark Energy Survey. The images and catalogs are 80% (50%) complete to limiting magnitudes of 22.0 (22.6) AB mag in the detection image, which is constructed from the weighted sum of the IRAC 3.6 and 4.5 micron images. The catalogs reach limiting sensitivities of 1.1 microJy at both 3.6 and 4.5 microns (1#, for R = 2" circular apertures).
The Spitzer Infrared Nearby Galaxy Survey is a comprehensive infrared imaging and spectroscopic survey of 75 nearby galaxies. Its primary goal is to characterize the infrared emission of galaxies and their principal infrared-emitting components, across a broad range of galaxy properties and star formation environments. SINGS provides new insights into the physical processes connecting star formation to the interstellar medium properties of galaxies and provides a vital foundation for understanding infrared observations of the distant universe and ultraluminous and active galaxies.
The Spitzer IRAC Equatorial Survey (SpIES) is a large-area survey of 115 sq. degrees in the Equatorial SDSS Stripe 82 field. SpIES achieves 5 sigma depths of 6.13 microJy (21.93 AB magnitude) and 5.75 microJy (22.0 AB magnitude) at 3.6 and 4.5 microns, respectively.
