Description:
The 2MASS Photometric Redshift catalogue (2MPZ) is constructed by cross-matching 2MASS XSC, WISE and SuperCOSMOS all-sky samples and employing the artificial neural network approach (the ANNz algorithm, Collister & Lahav 2004), trained on several redshift surveys (2MRS, SDSS, 6dFGS, 2dFGRS and ZCAT). The derived photometric redshifts have errors nearly independent of distance, with an all-sky accuracy of Ïz = 0.015, and a very small percentage of outliers. These redshift estimates have a typical precision of 12% for all the 2MASS XSC galaxies that lack spectroscopy. The resulting 2MPZ sample contains almost 1 million galaxies with a median redshift of z=0.07. This catalogue is described in Bilicki et al. 2014, ApJS, 210, 9.

Description:
The Millennium Galaxy Catalogue (MGC) is a 37.5 deg2, medium-deep, B-band imaging survey obtained with the Wide Field Camera on the INT. The survey region is a long, 35 arcmin wide strip along the equator, covering from 10h 00m to 14h 45m and is fully contained within the regions of both the Two Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

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).
