A deep 38-MHz radio survey of the area delta >+60.
Abstract
A deep survey of radio sources has been performed at a frequency of 38 MHz. The survey covers an area of about 1 sr north of δ = + 60^deg^ and contains reliable fluxes for about 5000 sources. The angular resolution is 4.5 x 4.5 cosec δ arcmin^2^, and the limiting flux density over much of the survey area is about 1 Jy. Both of these figures are an improvement by nearly an order of magnitude on previous surveys at this frequency. This paper describes the methods of data reduction and presents contour plots and a source list for the entire area.
