Descripción
We have successfully reduced the polarization data from the recently published 21 cm continuum survey of the southern sky carried out with a 30-m antenna at Villa Elisa (Argentina). We describe the reduction and calibration methods of the survey. The result is a fully sampled survey, which covers declinations from -90 degrees to -10 degrees with a typical rms-noise of 15 mK TB. The map of polarized intensity shows large regions with smooth low-level emission, but also a number of enhanced high-latitude features. Most of these regions have no counterpart in total intensity and indicate Faraday active regions.
