The Westerbork Northern Sky Survey (<i>WENSS</i>) is a low-frequency
radio survey that covers the whole sky north of delta=30 degree at a
wavelength of 92 cm to a limiting flux density of approximately 18 mJy
(5 sigma). This survey has a resolution of 54" x 54" cosec (delta)
and a positional accuracy for strong sources of 1.5''.
