Abstract:
We have observed 250 of the 258 southern sources in the complete 5GHz
1Jy sample by Kuehr et al. (1981, Cat. VIII/5) using the Australia
Telescope Compact Array (ATCA) at 18.5GHz. This paper focuses on the
polarization properties of this sample, while other properties will be
addressed in a future paper.
Description:
The observations were performed in three runs during March 2002. The
total observing time was 48 hours: 24 hours on March 20-21, 10 hours
on March 21-22 and 14 hours on March 27-28.
53 sources have been rejected after data reduction.
