Abstract:
We present the results of a deep 610-MHz survey of the 1H
XMM-Newton/Chandra survey area with the Giant Metre-wave Radio
Telescope. The resulting maps have a resolution of ∼7arcsec and an rms
noise limit of 60Jy. To a 5σ detection limit of 300Jy, we detect
223 sources within a survey area of 64arcmin in diameter. We compute
the 610-MHz source counts and compare them to those measured at other
radio wavelengths.
Description:
In 2004 August, the 1H field (RA=01:45:27 and DE=-04:34:42) was
observed for approximately 4.5h at 610MHz with the GMRT.
Observations were carried out in dual band, spectral line mode, the
former to maximize bandwidth and the latter to minimize chromatic
aberration. Two sidebands, each of 128 spectral channels of 125kHz,
were centred on 602 and 618MHz to give a total of 32MHz bandwidth,
with two independent circular polarizations recorded.
