A 2003 cross-identification of the ROSAT All-Sky Survey Bright Source Catalog with the NRAO VLA Sky Survey created a sample of 1,557 bright X-ray sources that are also radio sources. The sample covers a 7.8 steradian solid angle of extragalactic sky with galactic latitude |b| > 15 degrees and declination > -40 degrees. This table was created by NASA's HEASARC based on source data from the CDS.
A network meta-analysis compares 36 randomized controlled trials involving 17,187 patients to evaluate the efficacy and safety of different adjuvant chemotherapy regimens for early-stage breast cancer. The analysis, conducted by Linxiaoxi Ma and published on figshare in 2026, assesses event-free survival, overall survival, and adverse effects from trials spanning up to 152 months of follow-up.
99 of 214 Pleiades stars were detected in X-rays within a single ROSAT PSPC field of ~1 degree radius, with upper limits computed for the remainder. This catalog lists stellar characteristics from the literature, including rotational data, alongside their X-ray properties. The database was created by NASA HEASARC in April 2002, derived from Tables 1 and 5 of the 1996 paper by Micela et al.
236 discrete X-ray sources were detected within the globular cluster-rich elliptical galaxy NGC 4278, using six Chandra ACIS-S observations totaling 458 ks of co-added exposure.

It aims to provide basic information on X-ray sources and their counterparts in UV, optical, IR, and radio wavelengths.
224 X-ray sources were detected in two deep XMM-Newton observations of the Upper Scorpius star-forming region.

This table was created by NASA's HEASARC in April 2008 based on source files from CDS Catalog J/A+A/477/593.
NASA HEASARC provides a catalog of 195 X-ray sources from two deep Chandra observations of the Rho Ophiuchi star-forming cloud. The data includes 71 detected flares from pre-main sequence stars and young brown dwarfs, with 306 total entries due to separate analyses for quiescent and flaring states. This table was created in February 2007 based on CDS catalog files.
A clinical dataset concerning ventilator-associated pneumonia (VAP) risk in patients requiring prolonged mechanical ventilation. It was created by Gabriel Arteaga-Troncoso and last updated on May 12, 2026. The dataset is stored in SAV format and has a size of 183.3 KB.
397 X-ray sources were detected in the Large Magellanic Cloud from 543 ROSAT HRI observations taken between 1990 and 1998. This catalog, created by Sasaki et al. and hosted by NASA HEASARC, includes 259 new detections and cross-references with other catalogs to provide hardness ratios and improved positional accuracy. 94 sources were identified with known objects, including stars, supernova remnants, and active galactic nuclei.
The Lockman Hole, a sky area of low Galactic line-of-sight column density, was observed by the XMM-Newton X-ray observatory between April 2000 and December 2002. The catalog lists positions, count rates, fluxes, hardness ratios, and partial optical classifications for 409 X-ray point sources detected in the central 0.196 square degrees. This table was created by NASA's HEASARC in May 2008 based on the CDS Catalog J/A+A/479/283.
A catalog of 720 X-ray observations for 493 galaxies, including 238 detections and 212 upper limits, from the Einstein Observatory's IPC and HRI instruments. The database was created by NASA's HEASARC in January 2002, incorporating data from pointed observations, serendipitous finds in the RSA and RC2 catalogs, and literature data for four nearby galaxies. It includes observations where galaxies were well-imaged within the field and cases where sources were at the edge or confused.
602,570 cataloged optical objects associated with radio and X-ray detections from instruments including NVSS, FIRST, XMM-Newton, and Chandra. The catalog, created by an author associated with [email protected] and hosted by NASA, provides sky coordinates, photometry, redshift, and calculated odds for object classification. It was last updated on 2026-03-13 and supersedes the previous Quasars.org (QORG) Catalog.
A 2017 catalog combines 180 ks of new and 370 ks of archival Chandra ACIS X-ray observations of the globular cluster 47 Tucanae from 2000, 2002, and 2014-2015. It identifies 370 point sources within the cluster's half-mass region, including 81 new sources, and associates some with known variable stars. The table was created by NASA HEASARC based on published catalog data.
K-BrowseComp is a Korean version of the BrowseComp benchmark for evaluating web-browsing agents. The dataset contains 300 handcrafted questions grounded in Korean contexts that require retrieving information across multiple Korean websites. It was created by native Korean speakers from the prometheus-eval organization and was last updated on June 1, 2026.
The ROSHRI table contains a list of X-ray sources detected by the ROSAT satellite's High Resolution Imager (HRI). Data centers in the US, Germany, and the UK screened the data and provided source reliability flags. This database table was last updated in August 2001.
