VIII/Deep 610-MHz GMRT Survey of the Lockman Hole (Garn+ 2010) ================================================================================ Further GMRT observations of the Lockman Hole at 610~MHz Garn T., Green D.A., Riley J. M., Alexander P. ================================================================================ ADC_Keywords: Radio sources ; Surveys Keywords: surveys - catalogues - radio continuum: galaxies Description: We present observations of the Lockman Hole, taken at 610 MHz with the Giant Metrewave Radio Telescope (GMRT). A further 26 pointings are added to 12 central pointings previous observed, to cover a total area of ~14 square degrees with a resolution of 6 x 5 arcsec^2^, PA +45 deg. The noise in the outer pointings is slightly worse than in the central pointings, and is considerably worse in the west, close to the very bright source 3C244.1. The final mosaic is presented, along with a catalogue of 4934 sources detected above 6 sigma.
