Abstract:
The Westerbork Radio Synthesis Telescope, WSRT, has been used to make
a deep radio survey of an ∼1.7degree2 field coinciding with the
AKARI north ecliptic pole deep field. The observations, data reduction
and source count analysis are presented, along with a description of
the overall scientific objectives.
The survey consisted of 10 pointings, mosaiced with enough overlap to
maintain a similar sensitivity across the central region that reached
as low as 21uJy/beam at 1.4GHz.
Description:
The radio observations presented in this paper were observed during
2004 with the WSRT operated at 20cm wavelength.
