A catalog of 1,055 quasars from the Large Bright Quasar Survey provides celestial positions, redshifts, and magnitudes. The data was compiled by NASA HEASARC in July 1999, incorporating corrections and updates from the original discovery papers. Positions were rederived using the PPM catalog for an improved reference frame.
A 1999 catalog from NASA HEASARC summarizes 397 bright, soft X-ray sources from the ROSAT All-Sky Survey at high galactic latitudes. It provides spectroscopic identifications for 108 sources, with the largest classes being AGN, magnetic cataclysmic variables, and hot white dwarfs. The database was created based on tables provided by the authors to CDS/ADC.
2,991 extragalactic supernovae discovered from 1885 until December 12, 2004, along with data on their host galaxies. The Sternberg Astronomical Institute compiled this catalog, with host galaxy data integrated from multiple astronomical catalogs like RC3, UGC, and PGC. NASA HEASARC created this table version in June 2005 based on a CDS source.
219 Fanaroff and Riley class I edge-darkened radio galaxies (FR Is) form the main FRICAT catalog, with an additional 14 smaller sources in the sFRICAT sample. The catalog was built by the authors by combining observations from the NVSS, FIRST, and SDSS surveys and is hosted by NASA HEASARC. This HEASARC table was created in February 2017 based on data from the Astronomy & Astrophysics website.
482 X-ray point sources were detected in the lenticular galaxy NGC 3115 using 1.1 megaseconds of Chandra observatory data. The catalog, produced by NASA, includes 136 candidate low-mass X-ray binaries in the field and 49 in globular clusters, with luminosities ranging from 10^36 to 10^39 erg s^-1. Observations were conducted in three epochs: 2001, 2010, and 2012.
Two-epoch observations from September 2005 and April 2006 imaged the central region of the Galaxy. The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSEII) Archive consists of point sources with a signal-to-noise > 5 in at least one band, provided by the National Aeronautics and Space Administration. Photometric uncertainty is typically less than 0.3 magnitudes.
NASA HEASARC provides a catalog of 7,855 radio-loud candidate gamma-ray emitting blazars, assembled from WISE mid-infrared sources cross-matched with radio surveys. The catalog classifies sources as BL Lacs, FSRQs, or mixed candidates, with 1,295 sources re-associated as confirmed blazars. This table was created in December 2014 based on a reference paper from the ApJS website.
Monitor Proportional Counter (MPC) data from the Einstein Observatory (HEAO-2) operational from 1978 to 1981. The instrument monitored 1 to 20 keV X-ray flux with a 1.5-degree field of view and an active area of 667 square cm. This catalog is provided by NASA HEASARC, with one duplicate entry removed in June 2019.
1898 H-alpha emission-line stars and small nebulae in the Small Magellanic Cloud were discovered in an objective-prism survey using the 0.90m Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory. The catalog, created by NASA HEASARC in November 1997, includes newly identified planetary nebulae, compact H II regions, and late-type stars. It provides continuum intensities, H-alpha emission line shapes and strengths, coordinates, and cross-identifications for the listed objects.
A database table of pointed telescope observations from NASA's Compton Gamma-Ray Observatory (CGRO), launched in 1991 and de-orbited in 2000. The table contains observations for Cycles 1 through 9, with viewing periods typically two weeks long, and was last updated in November 2001. The information was provided by the Compton Observatory Science Support Center, with galactic coordinates added by the HEASARC in 2005.
Pathogen detection results from 400 pharyngeal swabs collected from influenza-like illness (ILI) patients in Guilin, China, between October 2023 and October 2024. The data, published by Jin Cao on figshare, includes detection rates for 18 pathogens, co-infection analysis, and epidemiological characteristics by age and season. The overall pathogen-positive rate was 74.0%, with Influenza, SARS-CoV-2, and Mycoplasma pneumoniae being the most common.
The Tartarus database provides systematically analyzed data from ASCA X-ray telescope observations of active galactic nuclei. It contains results for 611 designated AGN observing sequences, including source and background event files, spectra, response files, images, and light curves. This version 3.1 was created by the Tartarus Team and ingested by NASA HEASARC in August 2005.
GLIMPSE3D is a catalog of infrared point sources from the Spitzer Space Telescope's IRAC instrument, mapping vertical extensions of the Galactic plane. The dataset is a subset of a larger archive, with sources meeting a signal-to-noise threshold and photometric uncertainty typically below 0.3 magnitudes. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
118,209 stars were selected from over 214,000 candidates to form the observing program for the European Space Agency's Hipparcos astrometry mission. The catalog includes positions, proper motions, magnitudes, colors, and, where available, spectral types, radial velocities, and variability information. This service is provided by NASA HEASARC.
Two-epoch infrared observations of the Galactic plane were taken in September 2005 and April 2006. The GLIMPSE II Archive contains point sources with a signal-to-noise >5 in at least one band, with photometric uncertainty typically under 0.3 magnitudes. This data was produced by the National Aeronautics and Space Administration (NASA).
The Galactic Plane survey covers 170 square degrees, contiguous over -10.5 âĪ l âĪ 90.5, |b| âĪ 0.5, with additional targeted regions in the outer Galaxy. It contains approximately 8,400 sources detected at 1.1 mm wavelength, with an rms noise level of 30 to 60 mJy beam-1.

NASA HEASARC provides a table from a 2010 spectroscopic study of 1080 nearby active M dwarfs, selected by correlating the 2MASS and ROSAT catalogs. The dataset includes derived spectral types, distances, H-alpha emission line measurements, X-ray luminosities, and tangential velocities for a subset of stars. Spectral types range from K5 to M6, with nearly half of the stars located within 50 parsecs.
