2006 data from the Tropical Warm Pool-International Cloud Experiment (TWP-ICE) in Australia provides simulated satellite orbits for ground validation. The dataset models sensor-specific observations from GMI and DPR instruments using high-resolution Cloud-Resolving Model profiles for atmospheric conditions, clouds, and precipitation.

4,784 unique broad absorption line quasars were identified from the Sloan Digital Sky Survey's third data release using an automated continuum-matching algorithm. The catalog, created by NASA HEASARC in July 2008, characterizes quasars through indices like balnicity and absorption, and parameters including trough width and outflow velocity. It is derived from samples of 16,883 quasars for C IV analysis and 34,973 quasars for Mg II analysis.
Observations from 2010 onward obtained with the NASA IRTF SpeX instrument covering the 0.7 to 2.5 micron near-infrared spectrum.

The research focused on mineralogically characterizing asteroids in a zone centered on the 3:1 resonance to identify their meteorite analogs.

The dataset covers the period from 2014-07-02 to 2014-08-01, with the prime target being comet 67P/Churyumov-Gerasimenko. This V1.0 version is the first release from the National Aeronautics and Space Administration, corrected after an October 2018 external peer review.

The dataset covers the energy range from 0.3 MeV to 51 MeV and was collected by a particle telescope developed by Germany in cooperation with NASA. Data spans the mission's operational range from 0.3 to 1.0 Astronomical Units (AU).
Hourly averaged fluxes of electrons, protons, and alpha particles measured by the Helios-A and Helios-B deep space probes. The data covers the energy range from 0.3 to 2.0 MeV for electrons, 4.0 to 51 MeV for protons, and 2.0 to 48 MeV for alpha particles, with measurements taken between 0.3 and 1.0 astronomical units from the Sun. This dataset was developed by the Federal Republic of Germany in cooperation with NASA, with detailed documentation available in Raumfahrtforschung, Volume 19, Number 5, 1975.
Helios-A and Helios-B spacecraft measured hourly averaged fluxes of electrons, protons, and alpha particles in interplanetary space from 0.3 to 1.0 Astronomical Units. The data, developed by the Federal Republic of Germany in cooperation with NASA, covers energy ranges from 0.3 to 2.0 MeV for electrons, 4.0 to 51 MeV for protons, and 2.0 to 48 MeV for alpha particles, with some channels providing standard deviations. Files are in ASCII format, each containing 10 hourly averages preceded by a header with start and stop times.
Helios 2 E6 data provides hourly averaged fluxes of electrons, protons, and alpha particles measured by the Helios-B deep space probe. The dataset, from NASA and the Federal Republic of Germany, covers the energy range 0.3 to 2.0 MeV for electrons, 4.0 to 51 MeV for protons, and 2.0 to 48 MeV for alpha particles, with measurements taken from 0.3 to 1.0 Astronomical Units from the Sun. It includes differential fluxes, integral fluxes for particles above certain energies, and for some channels, the standard deviations of the averages.
The SMC&BridgeClustersCatalog is the Small Magellanic Cloud and Inter-Magellanic Cloud 'Bridge' portion of the 'Revised and Extended Catalog of Magellanic System Clusters, Associations, and Emission Nebulae'. It contains 1188 extended objects identified from the ESO/SERC R and J Sky Survey Atlases, including 544 star clusters, 343 associations, and 291 emission nebulae. This database table was created by NASA's HEASARC in February 1998 based on a version obtained from the CDS catalog J/ApJS/101/41.
August 2012 catalog lists all confirmed globular clusters, candidate clusters, and previously misclassified objects in the Andromeda Galaxy (M 31). The catalog was created by the HEASARC in November 2014 based on Version 5 of the Revised Bologna Catalogue. It includes classification flags for objects such as genuine clusters, foreground stars, background galaxies, and HII regions.
517 discrete X-ray sources were cataloged in a 6 by 6 degree field covering the Small Magellanic Cloud. The catalog was derived from pointed ROSAT PSPC observations performed between October 1991 and May 1994 and is maintained by NASA HEASARC. For 158 sources, a likely type is given, including 46 candidate background active galactic nuclei.
The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey covering 10 square degrees in the Boötes field. It was conducted using the IRAC instrument on the Spitzer Space Telescope as a Cycle 4 Legacy project. The delivery consists of 20 band-matched catalogs reporting Vega magnitudes in four infrared bands.
Four-epoch infrared survey of 10 square degrees in the Boötes field, permitting the selection of variable and high proper motion objects over years.

Over one hundred individual pointing and field scans were performed by the eROSITA X-ray telescope between mid-September and mid-December 2019. This catalog lists observations from the Calibration and Performance Verification program, categorized into Survey fields, Magellanic Clouds, Galactic fields, and Extragalactic fields. NASA HEASARC produced this database table in July 2023 based on information from the German eROSITA Consortium.

The catalog is complete for stars brighter than visual magnitude 8 and includes fainter stars, providing cross-identifications, coordinates, photometry, and group membership information. This table was created by the HEASARC in February 2009 based on source data from the Centre de Données astronomiques de Strasbourg (CDS).
Two ~0.5 square degree fields in the Coma cluster of galaxies were observed at 1.4 GHz using the Very Large Array (VLA) over five days in June 2006. The resulting catalog contains 1030 radio sources detected at or above a 5-sigma significance threshold, with 628 within the combined observed area, and includes optical identifications from the Sloan Digital Sky Survey (SDSS). This table was created by NASA's HEASARC in December 2011 based on source files from the CDS catalog.

It contains X-ray properties for 1754 point sources, including 1183 candidate cluster members, derived from three Chandra/ACIS-I observations totaling approximately 238 ks. The data was produced by researchers analyzing the correlation between X-ray emission and stellar evolutionary stages in young clusters.
