The "Spitzer Extragalactic Representative Volume Survey" (SERVS) Exploration Science program conducted deep IRAC 3.6 and 4.5 micron observations of five extragalactic fields (ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS).
Objects in the single band catalogs are not required to have any counterparts in the other band. They are cut at CSNR > 5 and also have the low coverage areas at the edges of the survey omitted (POLY=1), resulting in a single-band reliability flag REL=1. They are thus deeper than the 2-band high reliability catalogs. These should be used if you are matching with a reliable catalog from another band (e.g. near-infrared), and simply want as many matches as possible, or are doing a statistical study.
The Spitzer Extragalactic First Look Survey is composed of 4 square degrees of imaging with MIPS and IRAC centered at J1718+5930. Ancillary data are available from a wide variety of optical and radio observatories.
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.
Spitzer IRAC/MUSYC Public Legacy Survey in the Extended Chandra Deep Field South

Description:
SIMPLE consists of deep IRAC observations (several hours per pointing) covering the 0.5 x 0.5 deg area surrounding the GOODS CDF-South. This low-background region of the sky has by far the best supporting data of any cosmological survey field of comparable area, with deep observations from the X-rays to the thermal infrared.
The Enhanced Products consist of two elements:
(1) A collection of 16,986 low-resolution, merged spectra
(2) A Catalog of extracted source positions, synthetic photometry in several bands, PSF profile widths, and other useful quantities.
These products were produced starting with the final SSC pipeline (ver. 18.18) bksub.tbl SL and LL spectra. The bksub.tbl spectra were extracted from the nod two minus nod one and nod one minus nod two background-subtracted basic calibrated data, using an aperture that expands linearly with wavelength. The calibrated fluxes are consequently strictly valid only for point sources.
Level 1 / Basic Calibration Data (BCD) from Spitzer Space Telescope. BCDs are the individual data frames that emerge [calibrated] from the Spitzer pipeline.
Level 2 or post Basic Calibrated Data (PBCD) from Spitzer Space Telescope. This products come from combining the individual data frames or BCDs [such as mosaics of individual pointings].
LVL consists of a sample of 258 galaxies, which have been mapped with both IRAC (4 bands) and MIPS (3 bands). In addition, ancillary data products consisting of images in the narrow-band H-alpha line emission and broad-band R (from the ground) and the UV continuum (2 bands) from GALEX are also available for many of the galaxies.
