VIII/Deep 610-MHz GMRT Survey of ELAIS-N1 region (Garn+ 2008) ================================================================================ A 610-MHz survey of the ELAIS-N1 field with the Giant Metrewave Radio Telescope - Observations, data analysis and source catalogue. Garn T., Green D.A., Riley J. M., Alexander P. =2008MNRAS.383...75G (SIMBAD/NED BIBCODE) ================================================================================ ADC_Keywords: Radio sources ; Surveys Keywords: surveys - catalogues - radio continuum: galaxies Description: Observations of the ELAIS-N1 field taken at 610 MHz with the Giant Metrewave Radio Telescope are presented. Nineteen pointings were observed, covering a total area of 9 square degrees with a resolution of 6 x 5 arcsec^2^, PA 45 deg. Four of the pointings were deep observations with an rms of ~40 uJy before primary beam correction, with the remaining fifteen pointings having an rms of ~70 uJy. The techniques used for data reduction and production of a mosaicked image of the region are described, and the final mosaic, along with a catalogue of 2500 sources detected above 6 sigma, are presented. This work complements the large amount of optical and infrared data already available on the region. For further details of the surveys and data analysis procedures please refer to the published paper referenced at the head of this file.
