Giant Metrewave Radio Telescope Lockman Hole 610-MHz Radio Source Catalog 2
This table contains a source catalog based on further observations of the Lockman Hole field, made with the Giant Metrewave Radio Telescope at 610 MHz with an angular resolution of 6 x 5 arcsec<sup>2</sup>. These complement this group's earlier observations of the central ~ 5 deg<sup>2</sup> of the Lockman Hole (Garn et al. 2008, MNRAS, 387, 1037, the HEASARC Browse table GMRTLHCAT) by covering a further ~ 8 deg<sup>2</sup> area, with an rms noise down to ~ 80 microJansky/beam (µJy/beam). A catalog of 4934 radio sources in both the inner and outer regions of the Lockman Hole is presented in this table. The earlier survey had 12 pointings covering ~ 5 square degrees in the center of the Lockman Hole, and herein 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, the images were made with a resolution of 6" x 5", at a position angle of +45 degrees. The majority of the new pointings have an rms noise of ~80 µJy/beam before the primary beam correction, but the noise in the west - particularly near the very bright source 3C244.1 - is worse. This table was created by the HEASARC in February 2012 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/BASI/38.103">CDS Catalog J/BASI/38.103</a> file gmrtlh2.cat.
