Description


This table contains a source catalog based on observations of the European Large-Area ISO Survey-North 2 (ELAIS-N2) field taken at 610 MHz with the Giant Metrewave Radio Telescope (GMRT). Thirteen pointings were observed, covering a total area of ~ 6 square degrees with a resolution of 6.5 x 5 arcsec<sup>2</sup>, position angle of +70 degrees. The rms noise at the center of the pointings is typically ~ 85 microJansky (µJy) before correction for the GMRT primary beam . The techniques used for data reduction and production of a mosaicked image of the region are described in the reference paper, where the final mosaic, along with a catalog of 1310 sources detected above a 6-sigma threshold, are presented. The survey complements existing radio and infrared data that are available for this region. For further details of the surveys and data analysis procedures, please refer to the published paper. This table contains the ELAIS-N2 catalog of 1310 detected 610-MHz radio sources. This table was created by the HEASARC in February 2012 based the source catalog of the Cambridge GMRT Survey of the ELAIS-N2 region which was obtained from the University of Cambridge Astrophysics Group Surveys and Catalogs website at <a href="http://www.mrao.cam.ac.uk/facilities/surveys/gmrt/elais-n2/">http://www.mrao.cam.ac.uk/facilities/surveys/gmrt/elais-n2/</a> file GMRT_EN2_dr1.dat. This is a service provided by NASA HEASARC .
