The authors have used the Very Large Array (VLA) in C configuration to carry out a sensitive 20-cm radio survey of regions of the sky that have been surveyed in the far-infrared...

The COSMOS weak lensing source catalog from Leauthaud et al. (2007).

The RASS X-Ray Variable Sources Catalog contains the results of a systematic search for variability among the ROSAT All-Sky Survey (RASS) X-ray sources. Lightcurves were...

The Great Observatories Origins Deep Survey (GOODS) aims to unite extremely deep observations from NASA's Great Observatories (Spitzer, Hubble and Chandra), ESA's Herschel and...

The authors of this catalog presented new Chandra constraints on the X-ray luminosity functions (XLFs) of X-ray binary (XRB) populations, as well as their scaling relations, for...

This database contains information on sources detected with the Einstein Observatory Image Proportional Counter (IPC), assembled for the Einstein Observatory Catalog (EOSCAT) of...

Soft X-ray (0.2 - 3.5 keV) measurements for all normal, massive, o-type stars surveyed with the Einstein Observatory are presented as a catalog containing 89 detections and 176...

The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey of 10 square degrees in the Boötes field of the NOAO Deep Wide-Field Survey using the IRAC instrument...

This table has an entry for all sources in the auxiliary QSO solution matched to the ICRF2 sources and passing all quality filters discussed in the corresponding documentation.

Empirical calibrations of the stellar age-rotation-activity relation (ARAR) rely on observations of the co-eval populations of stars in open clusters. The authors used the...

This table contains optical spectroscopic identifications of X-ray sources in ~3 square degrees of the XMM-Large Scale Structure survey (XMM-LSS), also covered by the Canada-...

The Space Telescope Imaging Spectrograph (STIS) was installed in HST on Feb. 14, 1997, replacing the GHRS spectrograph. STIS provides spectra and images at ultraviolet and...

The SAXNFILOG database contains the SAX Narrow Field Instruments (NFI) approved pointings, but it also served as an observations log. It includes data taken during AO1, AO2,...

The Spitzer Wide-area InfraRed Extragalactic survey (SWIRE), the largest Spitzer Legacy program, is a wide-area, imaging survey to trace the evolution of dusty, star-forming...

The aim of this study was to find an explanation for the remarkable morphology of the central part of the S254-S258 star forming complex. The authors performed a deep Chandra...

The XMM-Newton X-ray observatory has performed repeated observations of the Chandra Deep Field-South (CDFS) in 33 epochs (2001 - 2010) through the XMM-CDFS Deep Survey (Comastri...

The GINGALAC database table contains a summary of the contents of the Ginga pointed observations. This table has been produced from the raw Ginga LAC First Reduction Files...

The Einstein Observatory (also known as HEAO-2 or HEAO-B) was operational from 1978 November 13 until 1981 April 25 when the attitude control system failed. The Solid State...

Planck was a European Space Agency (ESA) mission, with significant contributions from the National Aeronautics and Space Agency (NASA). It was the third generation of space-...

The Chandra archival data are a valuable resource for various studies on different X-ray astronomy topics. In this paper, the authors utilize this wealth of information and...
