LBA-ECO CD-06 provides two distinct but related datasets from the Large-Scale Biosphere-Atmosphere Experiment in Amazonia. The first contains measurements of carbon dioxide flux, gas transfer velocity, and partial pressure from 75 river and stream sites across the Amazon system between July 2004 and January 2007. The second dataset includes forest biomass measurements, specifically leaf area index, dendrometry, and litterfall mass, collected at the km 67 site in Tapajós National Forest, Brazil, during 2004.
A dataset of differentially accumulated metabolites in Castanea mollissima (Chinese chestnut) leaves, comparing cultivars with varying resistance to the pest Oligonychus ununguis. The dataset was authored by Xinfang Zhang and is available under a CC-BY-4.0 license. It was last updated on May 15, 2026.
Partial spectral data plots from S. Sawyer's 1991 PhD thesis, 'A High Resolution Spectroscopic Survey of Low Albedo Main Belt Asteroids'. The dataset is hosted by the National Aeronautics and Space Administration and was last updated on the platform in April 2026. It includes files in JPEG and HTML formats.
NASA HEASARC provides FITS lightcurves from the A detector of the GCXSE experiment aboard the OSO-8 satellite, which operated from June 1975 to September 1978. The A detector collected data in the 2-60 keV energy band, viewing portions of the sky perpendicular to the earth-sun line. This data originates from a non-solar objective instrument mounted on the spacecraft's rotating wheel section.
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. This catalog from NASA HEASARC lists planned and validated observations from the telescope, which operates in the 3 to 79 keV energy band. The table is automatically updated and includes information on observation status and public data availability.
A catalog of X-ray point sources detected in a deep XMM-Newton observation of the Fornax dwarf spheroidal galaxy. The table was created by NASA's HEASARC in February 2013 based on results published in the Astronomy & Astrophysics journal. It includes sources likely to be background active galactic nuclei, potential associations with a variable star and globular clusters, and constraints on accretion parameters for a putative intermediate-mass black hole.
GLIMPSE3D is a Galactic plane mapping project using the Spitzer Space Telescope Infrared Array Camera (IRAC). The More Reliable Archive provides higher-reliability point sources from the single-visit epoch 2, requiring two detections in adjacent bands. The data was produced by the National Aeronautics and Space Administration and was last updated on 2026-03-13.
A catalog of 34 optically identified galaxy clusters discovered in a serendipitous X-ray survey of 86 ROSAT PSPC fields. The survey covers 16.2 square degrees and includes a complete, statistically well-defined sample of 22 clusters from 14.1 square degrees. NASA HEASARC created this online catalog in May 2003 based on tables from Perlman et al. (2002).
271 high-energy gamma-ray sources detected by the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma-Ray Observatory between April 1991 and October 1995. The catalog includes 5 pulsars, 66 high-confidence blazars, and 170 unidentified sources, with data reprocessed to correct errors from prior versions. This database table was created and is maintained by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC).
398 young stellar objects (YSOs) in the Orion Nebula Cluster are cataloged with JHK and IRAC infrared photometry and protostar classifications. The data was assembled from observations by the HST Treasury Program, WFI at ESO 2.2m, ISPI at CTIO 4m, and Spitzer IRAC. This online catalog was created by NASA HEASARC in October 2010 based on tables from the reference paper.
The Spitzer Science Center and Infrared Science Archive released enhanced imaging products from the Spitzer Heritage Archive. These products include mosaic images and a source list of photometry for compact sources from the IRAC and MIPS instrument channels. The source list prioritizes reliability over completeness, meaning it is not complete at any flux density.
Approximately 590 square degrees of sky, concentrated on the Large and Small Magellanic Clouds, were scanned with long-exposure infrared observations during the final months of the 2MASS observatory. The National Aeronautics and Space Administration created this metadata table for scans that probe about one magnitude deeper than the main survey. Data was last updated in March 2026.
The 2dF QSO Redshift Survey (2QZ) catalog covers 721.6 square degrees of sky in two declination strips across the South and North Galactic Gaps. It contains 44,576 color-selected objects, including 23,338 quasars, 12,292 galactic stars, and 4,558 compact narrow emission-line galaxies, based on Anglo-Australian Telescope 2dF spectroscopic observations from 1997 to 2002. This catalog, created by NASA HEASARC in 2010, is described as the largest homogeneous QSO catalog at its faint magnitude limits.
GLIMPSE 3D is a large-area infrared survey of the Galactic plane conducted by the Spitzer Space Telescope. The Epoch 1 Catalog is a subset of the project's Archive, containing point sources with a signal-to-noise ratio greater than 5 in at least one band and photometric uncertainty typically under 0.3 magnitudes. The data was produced by the National Aeronautics and Space Administration and was last updated in March 2026.
The GLIMPSE II Epoch1 Catalog is a subset of point source data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire, produced by the National Aeronautics and Space Administration. It contains infrared observations of the central region of the Galaxy, with latitude coverage varying from ±1° to ±2° and excluding the Galactic center. The catalog is derived from two-epoch observations taken in September 2005 and April 2006, with sources requiring a signal-to-noise > 5 in at least one band.
