Giant Metrewave Radio Telescope ELAIS-N1 Field 610-MHz Radio Source Catalog

Nineteen pointings were observed, covering a total area of ~ 9 square degrees with a resolution of 6 x 5 arcsec<sup>2</sup>, position angle of +45 degrees. Four of the pointings were deep observations with an rms of ~ 40 microJansky (µJy) before primary beam correction, with the remaining fifteen pointings having an rms of ~ 70 uJy.

The techniques used for data reduction and production of a mosaicked image of the region are described in the reference paper, where the final mosaic, along with a catalog of 2500 sources detected above a 6-sigma threshold, are presented. This work complements the large amount of optical and infrared data already available on the region. In their paper, the authors calculate 610-MHz source counts down to 270 uJy, and find further evidence for the turnover in differential number counts below 1 mJy, previously seen at both 610 MHz and 1.4 GHz.
