... Radio observations of the Marano Field , carried out with the Australian Telescope Compact Array at 20 and 13 cm, are presented. ... Excellent optical and X-ray data relative to this field are available. We plan to obtain a deep X-ray, optical and radio survey in order to study the nature of the sub-mJy population (a population of radio sources at very low radio fluxes) and the energy distribution and evolutionary properties of faint radio galaxies and AGNs. ... The radio data . ... 1992) ). ...
