Scientific paper

The Southern Twenty-centimeter All-sky Polarization Survey (STAPS) is proposed as a piggyback project on the S-band Polarization All-sky Survey (P560). STAPS will survey the polarized radio continuum sky from 1300 to 1800MHz at 15' resolution to probe Galactic magnetism through Faraday rotation, mostly at higher latitudes where Faraday rotation is modest. Combination of STAPS with S-PASS will significantly enhance the quality of obtainable rotation measures, especially at high latitudes. Furthermore, STAPS is envisioned to be an essential part of a global effort to map the polarized radio sky at almost contiguous frequencies from 80MHz to 2400MHz. With this frequency coverage, individual RM components along sightlines can be deconvolved with unprecedented RM resolution and dynamic range, enabling three-dimensional mapping of the Galactic magnetic field. The 1.4GHz H-OH receiver used for STAPS is to be placed off-axis next to the 2.3GHz S-PASS receiver, so that data of both surveys can be simultaneously taken. Calculations of the radiation and instrumental polarization patterns across the beam for the off-axis receiver indicate that the expected instrumental polarization is between 0.3% and 0.9% (without corrections). We request zero observing hours this semester.
