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.
