J/MNRAS/272/699 J/MNRAS/272/699 The 5C13 deep radio survey C R Benn Mon. Not. R. Astron. Soc. 272 699 1995 1995MNRAS.272..699B radio continuum: general surveys A deep 0.4-GHz survey of a 4deg-diameter region in Hercules is reported. 232 sources brighter than 9.5 mJy were detected. In a simultaneous 1.4-GHz survey of the concentric area 1deg in diameter, 45 sources brighter than 1.7 mJy were detected. The differential 0.4-GHz radio source count is presented; it is in good agreement with that from other 5C surveys. This survey brings to 3220 the number of 0.4-GHz sources catalogued by the published 5C surveys.
