Abstract:
We present further observations of the Lockman Hole field, made with
the Giant Metrewave Radio Telescope at 610MHz with a resolution of
6x5arcsec^2^. These complement our earlier observations of the central
5deg^2^ by covering a further 8deg^2^, 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 +45deg]. 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.
