FIFI-LS was an integral field, far-infrared spectrometer. The instrument included two independent grating spectrometers sharing a common field of view (FOV). The short wavelength spectrometer (blue channel) operated in the 51 - 120 um wavelength region, and the long wavelength spectrometer (red channel) covered 115 - 200 um. The spectral resolution ranged from 600 to 2,000 dependent on the observed wavelength, with higher values towards the long wavelength ends of each spectrometer.
FLITECAM was an infrared camera operating in the 1.0 - 5.5 um waveband. It consisted of a 1024x1024 InSb detector with 0.475"x0.475" pixels and used refractive optics to provide an 8' diameter field of view. The instrument had a set of filters for imaging, and grisms for moderate resolution spectroscopy. The filter suite consisted of standard Barr filters used for imaging at J, H, K, L and M in one filter wheel. A second filter wheel held a selection of narrow-band imaging filters including Pa-alpha, Pa-alpha continuum, 3.07 um H2O ice, 3.3 um PAH, L-narrow and M-narrow. Additionally there were order sorting filters for use with the grisms. A selection of three grisms was available to provide medium resolution (R ~ 1500) spectra over the entire wavelength range.

FORCAST was a dual-channel mid-infrared camera and spectrograph sensitive from 5 - 40 um. Spectroscopy was also possible using a suite of grisms, which provided coverage from 5 - 40 um with a low spectral resolution of R ~ 200.

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.
The German REceiver for Astronomy at Terahertz Frequencies (GREAT) was a modular heterodyne instrument with multiple configurations that provided high-resolution spectra (up to R = 1e8) in several frequency windows between 0.4900-4.7448 THz.
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.
