1420MHz radio continuum survey of the southern sky

DOI

The results of an absolutely calibrated radio continuum survey of the South Celestial Hemisphere at a frequency of 1420MHz are presented. Contour maps show the area 0h<=RA<=24h for the declination range -90{deg} to -10{deg}. Contour steps (50mK T_B_; 3xrms noise) and angular resolution (HPBW 35.4') of the maps match the already existing Stockert telescope Northern Sky Survey at the same frequency (Reich 1982A&AS...48..219R ; Reich & Reich 1986A&AS...63..205R). We compare flux densities of compact and extended sources with published data from the Parkes 64-m telescope and find excellent agreement in general. The survey maps are sensitive enough to constrain synchrotron and thermal emission components which might influence studies of the cosmic microwave background.
