- Description:
- The SuperCOSMOS data held in the SSA primarily originate from scans of Palomar and UK Schmidt blue, red and near-IR southern sky surveys. The ESO Schmidt R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also been scanned and provide a 1st epoch red measurement. Further details on the surveys, the scanning process and the raw parameters extracted can be found on the further information link. The SSA is housed in a relational database running on Microsoft SQL Server 2000. Data are stored in tables which are inter-linked via reference ID numbers. In addition to the astronomical object catalogues these tables also contain information on the plates that were scanned, survey field centres and calibration coefficients. Most user science queries will only need to access the SOURCE table or to a lesser extent the DETECTION table.

- Description:
- The Two Micron All Sky Survey (2MASS) will provide a uniform survey of the entire sky at three near-infrared wavebands: J(lambdaeff = 1.25 micrometers), H(lambdaeff = 1.65 micrometers), and Ks(lambdaeff = 2.16 micrometers). A major goal of the survey is to probe large scale structures in the Milky Way and in the Local Universe, exploiting the relatively high transparency of the interstellar medium in the near-infrared, and the high near-infrared luminosities of evolved low- and intermediate-mass stars.Home page at http://pegasus.phast.umass.edu/

- Publisher:
- WFAU
- Description:
- This DSA hosts data release 8 of the UKIRT Infrared Deep Sky Survey housed at the Wide Field Astronomy Unit at the Univeristy of Edinburgh. In order to access this data you need to contact Mark Holliman at msh@roe.ac.uk to be added to the authorized users list. This catalog contains WFCAM data primarily originating from the five UKIDSS surveys: Large Area Survey, Galactic Plane Survey, Galactic Clusters Survey, Deep Extragalactic Survey and the Ultra Deep Survey (see the www.ukidss.org for survey descriptions)

- Description:
- Database that resolves how to access records in problematic datasets. There are several distinct types of table: 1) Planetary observations stored in NASA's PDS and ESA's PSA; 2) Small FOV, pointed solar instruments; 3) Observations in the Global H-alpha Network.

- Title:
- XMM-Newton Serendipitous Source Catalogue (2XMM)
- Short Name:
- 2XMM
- Date:

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- XMM is the second comprehensive catalogue of serendipitous X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory. The 2XMM catalogue is the largest X-ray source catalogue ever produced, containing almost twice as many discrete sources as either the ROSAT survey or pointed catalogues. 2XMM complements deeper Chandra and XMM-Newton small area surveys, probing a much larger sky area.

- Description:
- The XMM-OM Serendipitous Ultra-violet Source Survey (SUSS) is a catalog of UV sources detected serendipitously by the Optical Monitor (OM) on-board the European Space Agency's (ESA's) XMM-Newton observatory. It has been created at the University College London's (UCL's) Mullard Space Science Laboratory (MSSL) on behalf of ESA and is a partner resource to the 2XMM serendipitous X-ray source catalogue. The catalog contains source detections drawn from 2,417 XMM-OM observations in up to three broad band UV filters made between 2000 February 24 and 2007 March 29. All datasets included were publicly available by 2007 May 01 but note that, due to screening criteria, not all public observations are included in this catalog. Taking account of substantial overlaps between observations, the net sky area covered independently is 29 - 54 square degreees, depending on UV filter. The primary content of the catalog is filter-dependent source positions and magnitudes, and these are accompanied by profile diagnostics and variability statistics. The XMM-OM SUSS catalog contains 753,578 UV source detections above a signal-to-noise threshold limit of 3-sigma which relate to 624,049 unique objects. A significant fraction of sources (12% - UVW2, 11% - UVM2, 11.% - UVW1) are visited more than once during XMM operation, and a large fraction of sources (38% - UVW2, 23% - UVM2, 22% - UVW1) are observed more than once per filter during an individual visit. UVW2, UVM2 and UVW1 refer to the filter bandpasses defined in the Source Properties: Filter Set section of the MSSL documentation for this catalog: <a href="http://www.mssl.ucl.ac.uk/~mds/XMM-OM-SUSS/SourcePropertiesFilters.shtml">http://www.mssl.ucl.ac.uk/~mds/XMM-OM-SUSS/SourcePropertiesFilters.shtml</a>. Consequently, the scope for science based on temporal source variability on timescales of hours to years is broad. The positional accuracy of the catalog detections is typically 1.0 arcsec (1-sigma confidence radius) with a median positional error of 0.67 arcsec. The median AB magnitude of the catalog detections in the three UV bands is 19.56 (UVW2), 20.23 (UVM2) and 20.69 (UVW1). 20% of sources have AB magnitudes fainter than 20.28 (UVW2), 20.97 (UVM2) and 21.54 (UVW1). As part of quality evaluation for the catalog, each field has been tested for astrometric accuracy and visually screened for cosmetic problems, compromising aspect anomalies, stray light, large extended sources and telemetry dropouts. Observations affected by these issues (11.2%) have been removed from the catalog sample. Furthermore, 2% of all observations were selected at random where each source in this sample was tested for falsehood, spuriousness and accuracy of quality flagging. The results of this detailed screening are included in the full documentation. The processing used to generate the catalog is based on the SAS8.0 pipeline developed for the pipeline reduction of all XMM observations. This version includes a number of significant improvements over the previous data processing system (as used by the SSC in routine processing of XMM-Newton data on behalf of ESA). These improvements include a more robust detection scheme for sources close to the limit of sky background, refined quality flagging and a higher success rate (90%) for refined aspect corrections.
