A catalog of 425 radio sources detected in a 10 square-degree region of the Bootes constellation. The data was produced by the Allen Telescope Array's Pi GHz Sky Survey (PiGSS) project, based on 75 daily observations over a 4-month period. This table, created by NASA's HEASARC in 2011, provides flux densities, source sizes, and spectral indices for the detected sources.
Roughly two billion objects are cataloged in this dataset from the Wide-field Infrared Survey Explorer (WISE). The catalog, produced by the National Aeronautics and Space Administration, is based on coadded imaging that is five times deeper than the previous AllWISE release. It detects sources about 0.7 magnitudes fainter and significantly increases galaxy counts at cosmological redshifts.
A catalog of 457 radio-continuum sources detected at 8640 MHz (3 cm) in the Small Magellanic Cloud. The catalog was created by NASA HEASARC in September 2014 based on combined Australia Telescope Compact Array (ATCA) data, with a sensitivity of 0.8 mJy/beam and a resolution of 20 arcseconds. Sources were identified using the MIRIAD task 'imsad' and visually confirmed as genuine point sources.
783 square degrees of high galactic latitude sky surveyed in the 0.05-2.0 keV soft X-ray band by NASA's EXOSAT imaging telescopes. The dataset includes 210 serendipitous sources defining a flux-limited sample, with 200 identified via optical and radio observations. The catalog was generated from the CMA database using a standard processing of the LE data and a sliding cell detection algorithm.
Over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects, were revealed by the Spitzer Space Telescope's SAGE survey of the Large Magellanic Cloud. The archive, provided by NASA, contains source fluxes from IRAC bands at 3.6, 4.5, 5.8, and 8.0 microns with a signal-to-noise threshold of 5. This data traces the life cycle of observable matter to study galaxy evolution.
389 distinct X-ray sources were detected in the Orion Nebula from three deep ROSAT HRI observations, covering a region containing over 1500 catalogued stars. The catalog, created by NASA HEASARC in 1997, concatenates optical counterpart data from the 1995 Gagne et al. research paper. It focuses on X-ray emission from late-type pre-main-sequence stars, with 324 sources having a single optical counterpart and 50 having multiple candidates.
The IXPE Master Catalog is a NASA HEASARC table listing targets and observations from the Imaging X-ray Polarimetry Explorer (IXPE) mission, launched in late 2021. It contains planned future targets and processed, validated observations, with data availability determined by a public date parameter. The catalog is generated by the IXPE Team and updated regularly.
The Large Magellanic Cloud was surveyed by the Spitzer Space Telescope's SAGE Legacy Project, which traces the life cycle of observable matter driving galactic evolution. The archive contains multi-epoch IRAC data for over 6 million sources, including evolved stars, young stellar objects, and the diffuse interstellar medium, providing averaged fluxes and variability indices. This data was produced by the National Aeronautics and Space Administration and was last updated in March 2026.
601 radio-continuum sources detected at 4800 MHz (6 cm) in the Small Magellanic Cloud. The catalog was created by the NASA HEASARC in September 2014 based on combined Australia Telescope Compact Array (ATCA) projects, with a sensitivity of 0.7 mJy/beam and a resolution of 30 arcseconds. Sources were identified using the MIRIAD task 'imsad' and visually confirmed as genuine point sources.
The Spitzer Space Telescope's SAGE project catalog reveals over 6 million infrared sources in the Large Magellanic Cloud, including approximately 150,000 evolved stars and 50,000 young stellar objects. This dataset, produced by NASA, contains separate source lists for Epoch 1 and Epoch 2 observations. It is designed to trace the life cycle of matter driving galactic evolution.
The Large Magellanic Cloud galaxy was surveyed by the Spitzer Space Telescope's SAGE Legacy Project to trace the life cycle of observable matter. The project has revealed over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects. This specific dataset is a calibration field archive from the survey, maintained by the National Aeronautics and Space Administration and last updated in March 2026.
From August 1977 to January 1979, the HEAO 1 satellite's A-2 Low Energy Detector surveyed over 95 percent of the sky in the 0.18-0.44 keV and 0.44-2.8 keV energy bands. The catalog lists 114 high-energy X-ray sources identified with a 6 sigma significance criterion, including galactic stellar sources, extragalactic sources, supernova remnants, and galactic bulge sources. This dataset was produced by the NASA HEASARC and includes counterpart identifications and publication references through the end of 1981.
Over 1000 pointed observations of approximately 350 different cosmic X-ray sources were performed by the Ginga satellite between 1987 and 1991. The raw data from its main instrument, the Large Area Counter (LAC), is provided in FITS format by NASA HEASARC. This database table was last updated by the HEASARC in August 2005.
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will observe several Deep Drilling Fields. This simulated lightcone catalog from the SHARK semi-analytic model covers 107.9 deg^2 to compare with the DeepDrill survey, which used the Spitzer Space Telescope to observe three LSST DDFs in the ECDFS, ES1, and XMM-LSS fields. The catalog includes a flux selection at the [3.6] band > 0.575 uJy and a redshift range of 0 < z < 6.
A Spitzer Space Telescope photometry catalog from the SAGE Legacy Project surveying the Large Magellanic Cloud. The project has revealed over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects.

Spitzer light curves for young stars in the NGC 2264 cluster, collected during the Warm Spitzer cycle 8 program in December 2011 to January 2012. The data were produced by the CSI 2264 project, which performed simultaneous photometric monitoring using the Spitzer IRAC and CoRoT satellites. The table contains many rows per object, representing multiple epochs of observation for objects with at least 15 good data points in an IRAC band.
The Spitzer South Ecliptic Pole MIPS Extended Source Catalog contains candidate extended sources identified from Spitzer/MIPS 24 and 70 Ξm imaging of an 11.5 square degree region near the South Ecliptic Pole.

The catalog was last updated on 2026-03-13.
The PPM database combines the PPM North and PPM South catalogs, a Bright Stars Supplement, and a 90,000 Stars Supplement. It provides positions and proper motions for 378,910 stars, effectively replacing older catalogs like SAO with improved precision on the J2000/FK5 coordinate system. The dataset was updated by the HEASARC in October 1999 based on ADC/CDS catalog data and is provided by the National Aeronautics and Space Administration.
