Description:
Small subset of the SuperCOSMOS Science Archive, useful for testing queries. 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 Rontgen Satellite Archive is an implementation of the ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision 1RXS) and the ROSAT All-Sky Survey Faint Source Catalogue (RASS-FSC, revision 1RXS). The RASS-BSC is derived from the all-sky survey performed during the first half year of the ROSAT mission in 1990/91. 18,811 sources are catalogued, with a limiting ROSAT PSPC countrate of 0.05 cts/s in the 0.1-2.4 keV energy band. The sources have a detection likelihood of at least 15 and contain at least 15 source photons. At a brightness limit of 0.1 cts/s (8,547 sources) the catalogue represents a sky coverage of 92%. The typical positional accuracy is 30 arcsec. The RASS-FSC is derived from the all-sky survey performed during the ROSAT mission in the energy band 0.1- 2.4 keV. 105,924 sources are catalogued and represent the faint extension to the RASS bright source catalogue. The sources have a detection likelihood of at least 7 and contain at least 6 source photons. (The likelihood of source detection is defined as L =-ln (1-P) , with P = probability of source detection).
