Abstract:
The 6th Cambridge survey of radio sources covers most of the sky north
of +30° with an angular resolution of 4.2x4.2cosecδarcmin2
and reaches a limiting flux density of 190mJy at 151MHz in the present
zone. In this paper the methods used to produce the survey maps from a
non-tracking telescope operating at declinations other than the north
celestial pole are described: this forms the basis for all future
papers in the series. Maps of a high galactic latitude region are
presented 30°<δ<51°, 08h30m<α<17h30m, together
with a list of 8278 sources in the 2030deg2 covered. A source count
over the range 200mJy<S(151)<100Jy is derived.

Note (1): Meaning of the symbols:
- (dash) = the peak was not strong enough to calculate the integrated flux
* (asterisk) = the peak flux was strong enough to qualify for integration,
but it has been integrated into a brighter adjoining peak.
