J/other/BASI/38.103 610-MHz survey of Lockman Hole with GMRT. II. (Garn+, 2010)

Further GMRT observations of the Lockman Hole at 610 MHz. Garn T.S., Green D.A., Riley J.M., Alexander P. <Bull. Astron. Soc. India, 38, 103-112 (2010)> =2010BASI...38..103G
ADC_Keywords: Radio sources ; Surveys Keywords: catalogues - surveys - radio continuum: galaxies Abstract: We present further observations of the Lockman Hole field, made with the Giant Metrewave Radio Telescope at 610MHz with a resolution of 6x5arcsec2. These complement our earlier observations of the central ∼5deg2 by covering a further ∼8deg2, with an r.m.s. noise down to ∼80uJy/beam. A catalogue of 4934 radio sources is presented Description: An earlier survey (Garn et al., 2008, Cat. J/MNRAS/387/1037) had 12 pointings covering ∼5 square degrees in the centre of the Lockman Hole, and here a further 26 pointings in the outer parts of the Lockman Hole are added, to cover a total of ∼14 square degrees. To match the earlier survey, images were made with a resolution of 6"x5", position angle +45{deg]. The majority of the pointings have an rms noise of ∼80uJy before primary beam correction, but the noise in the west - particularly near the very bright source 3C244.1 - is worse. File Summary:
