| The Q and U maps are the combination of the 26-m DRAO (Dominion Radio Astrophysical Observatory) and the 30-m Villa Elisa polarization survey, at 1.4 GHz (21 cm), with an angular resolution of 36'. Units of the maps are ''mKTB''. | The Q and U maps are the combination of the 26-m DRAO (Dominion Radio Astrophysical Observatory) and the 30-m Villa Elisa polarization survey, at 1.4 GHz (21 cm), with an angular resolution of 36'.

| - | The Villa Elisa 30-m telescope was used to map the southern sky simultaneously in continuum and linear polarization, yielding a fully sampled map of the 21cm linearly polarized emission for declinations between -10 and -90 degrees. Data in the overlap region between -10 and -27 degrees was used to match the Villa Elisa survey's zero-level with that of the DRAO 1.4 GHz linear polarization survey. | + | The Villa Elisa 30-m telescope was used to map the southern sky simultaneously in continuum and linear polarization, yielding a fully sampled map of the 21cm linearly polarized emission for declinations between -10 and -90 degrees.
