Spitzer Extragalactic First Look Survey IRAC Ch2 Verification Field Catalog
The Extragalactic First Look Survey is composed of 4 square degrees of imaging with MIPS and IRAC centered at J1718+5930, with extensive ancillary data from ground-based optical and radio telescopes. As one of the first observations made with Spitzer after the completion of Science Verification at the end of 2003 November, the aim of this 67 hr survey was to characterize the extragalactic source populations observed with Spitzer down to sub-millijansky levels in the mid-infrared.

Spitzer Wide-area InfraRed Extragalactic Survey ELAIS-N2 MIPS24 Single-Band Catalog
The Spitzer Wide-area InfraRed Extragalactic survey (SWIRE), the largest Spitzer Legacy program, is a wide-area, imaging survey to trace the evolution of dusty, star-forming galaxies, evolved stellar populations, and AGN as a function of environment, from redshifts z~3 to the current epoch. SWIRE surveys 6 high-latitude fields, totaling ~50 sq. deg. in all 7 Spitzer bands: 3.6, 4.5, 5.8, and 8 microns with IRAC and 24, 70, and 160 microns with MIPS (Lonsdale et al. 2003). The SWIRE Legacy Extragalactic Source Catalogs will eventually contain in excess of 2 million IR-selected galaxies, from those dominated by the light of stellar populations detected primarily by IRAC, to starbursts, ultra-luminous infrared galaxies and AGN detected also by MIPS.The main SWIRE catalogs for 24 micron data are the Optical-IRAC-MIPS24 bandmerged catalogs. The bandmerged catalogs require a detection in the shortest IRAC band (3.6 microns). The SWIRE project has produced single-band 24 micron catalogs to cover regions that lie outside the IRAC images, and to include sources that for some reason were not associated with a 3.6 micron detection.
Spitzer Extragalactic Representative Volume Survey XMM-LSS 2-band Catalog
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.
Spitzer South Ecliptic Pole MIPS 70 micron Point Source Catalog
The Spitzer/MIPS 24 and 70 μm imaging of an 11.5 square degree region near the South Ecliptic Pole (SEP) has been carried out in order to complement sub-millimeter wavelength observations (250-500 μm) of the same region of sky taken with the Balloon-borne Large Aperture Sub-millimeter Telescope (BLAST), with the goal of better characterizing the nature of sub-millimeter selected galaxies and their role in galaxy evolution. This field has also been extensively mapped at other wavelengths, and will be imaged from 100-500 μm as part of the Herschel Multi-tiered Extragalactic Survey (HerMES). Source detection and photometry were performed using the APEX software within the MOPEX package. Source candidates with S/N > 6 and reduced chi-squared values less than or equal to three (93% of the sources) are considered reliable detections. The remaining source candidates were then inspected (see Scott et al. 2010 for details) and false positives were removed from the catalog.

Spitzer Space Telescope Observation Log
This database table contains the Spitzer Space Telescope (SST) log of executed and scheduled observations, and is updated on a weekly basis. Spitzer is the fourth and final element in NASA's family of Great Observatories and represents an important scientific and technical bridge to NASA's Astronomical Search for Origins program. The SST Observatory carries an 85-cm cryogenic telescope and 3 cryogenically cooled science instruments capable of performing imaging and spectroscopy in the 3.6 to 160 micron (µm) range. Spitzer was launched on a Delta 7920H from Cape Canaveral into an Earth-trailing heliocentric orbit in August 2003. While the Spitzer cryogenic lifetime requirements are 2.5 years, current estimates indicate that achieving a goal of a 5-year cryogenic mission is possible. For more overview information, refer to the Spitzer Science Center (SSC) Overview at <a href="http://ssc.spitzer.caltech.edu/spitzermission/">http://ssc.spitzer.caltech.edu/spitzermission/</a>. The purpose of this HEASARC table is to help users, particularly those in the high-energy astronomy community, learn about which targets Spitzer has observed or will shortly observe. This table does not at this time have links from table entries to Spitzer data products. Once a particular Spitzer dataset of interest is identified, the SSC Archives/Analysis web page at <a href="http://ssc.spitzer.caltech.edu/archanaly/">http://ssc.spitzer.caltech.edu/archanaly/</a> should be used to access the dataset. The information in this table has been derived from the following files obtained from the SSC website: <p> The schedule of Spitzer science observations as executed: <pre> <a href="http://irsa.ipac.caltech.edu/data/SPITZER/docs/files/spitzer/spitzer_obslog.txt">http://irsa.ipac.caltech.edu/data/SPITZER/docs/files/spitzer/spitzer_obslog.txt</a> </pre> The list of all approved Spitzer science programs: <pre> <a href="http://irsa.ipac.caltech.edu/data/SPITZER/docs/files/spitzer/spitzer_programs.txt">http://irsa.ipac.caltech.edu/data/SPITZER/docs/files/spitzer/spitzer_programs.txt</a> </pre> Notice that this table contains primarily observations (identified by their AOR key value) from the first URL above. A given observation should appear only once in this HEASARC table. The HEASARC checks these URLs for modifications periodically and updates the table whenever changes are detected.

Point Sources from a Spitzer/IRAC Survey of the Galactic Center
Spitzer/IRAC observations of the central 2.0 deg by 1.4 deg (~ 280 pc by 200 pc) of the Galaxy were obtained at 3.6-8.0 microns in Cycle 1 (GO 3677, PI: Stolovy). These data represent the highest spatial resolution (~2 arcsec) and sensitivity uniform large-scale map made to date of the Galactic Center at mid-infrared wavelengths.A point source catalog of 1,065,565 objects was obtained. The catalog includes magnitudes for the point sources at 3.6, 4.5, 5.8, and 8.0 microns, as well as JHK photometry from 2MASS. The point source catalog is confusion limited with average limits of 12.4, 12.1, 11.7, and 11.2 magnitudes for [3.6], [4.5], [5.8], and [8.0], respectively. The confusion limits are spatially variable because of stellar surface density, background surface brightness level, and extinction variations across the survey region. More details about the point source catalog can be found at Ramirez et al. 2008.

Dust in Nearby Galaxies with Spitzer (DUSTiNGS) Good Source Catalog
DUSTiNGS consists of a sample of 50 dwarf galaxies within 1.5 Mpc, which have been mapped with IRAC channels 1 and 2 (3.6 and 4.5 microns). The sample consists of 37 dwarf spheroidal, 8 dwarf irregular, and 5 transition-type galaxies.The DUSTiNGS data release includes images and source catalogs based on uniform Spitzer 3.6 and 4.5 micron observations. The catalogs are available in "full" and "good" versions, where quality cuts based on photometric accuracy and source morphology have been applied to the latter. See Boyer et al. (2015) for details.
Spitzer Archival Far-Infrared Extragalactic Survey (SAFIRES) MIPS 160 micron Catalog
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.
Spitzer Extragalactic First Look Survey WIYN/Hydra Spectroscopic Catalog

This catalog presents data on the WIYN/Hydra spectra described in Marleau et al. (2007).
Spitzer Deep Wide-Field Survey 5.8 micron Epoch 4 Catalog
The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey of 10 square degrees in the Boötes field of the NOAO Deep Wide-Field Survey using the IRAC instrument on the Spitzer Space Telescope. SDWFS, a Spitzer Cycle 4 Legacy project, occupies a unique position in the area-depth survey space defined by other Spitzer surveys. The four epochs that make up SDWFS permit - for the first time - the selection of infrared-variable and high proper motion objects over a wide field on timescales of years. Because of its large survey volume, SDWFS is sensitive to galaxies out to z ~ 3 with relatively little impact from cosmic variance for all but the richest systems. The SDWFS data sets will thus be especially useful for characterizing galaxy evolution beyond z ~ 1.5.The delivery consists of four band-matched catalogs for each of the four epochs and for the total SDWFS coadd data, a total of 20 catalogs. Vega magnitudes are reported for each IRAC band: 3.6, 4.5, 5.8, and 8 microns. Each source was measured three ways: 4 arcsec diameter aperture, 6 arcsec diameter aperture, and Kron radius aperture (MAG_AUTO in SExtractor). Source coordinates correspond to 2MASS catalog positions to within 0.2 arcsec. The tabulated uncertainties are twice the SExtractor (statistical only) uncertainties as an attempt to account for systematic uncertainties.
Spitzer Extragalactic Representative Volume Survey ELAIS-S1 2-band Catalog
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).The 2-band high reliability catalogs are matched [3.6] and [4.5] catalogs, with the low coverage areas near the edges of the survey omitted (POLY_12=1). These catalogs should be used if you are using SERVS to select your sample, as objects in this catalog should be highly reliable (>99.9%). To appear in the catalog objects must appear in both bands, and the detection in one band must be > 10-sigma in CSNR, where CSNR is the coverage-weighted signal-to-noise ratio.
