Description:
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.

Note (1): measured at 0.4 GHz or, if detected at higher frequency, at 1.4 GHz
Note (2): S0.4 must be multiplied by this factor to recover the apparent
flux density S'0.4 with which the source appears on the synthesized
map, and hence the signal-to-noise ratio
