Sun et al. present data processing and verification of the Southern Twenty-centimetre All-sky Polarization Survey (STAPS) conducted with Murriyang, the Parkes 64-m telescope. The survey covers the southern sky between declinations of −89 degrees and 0 degrees, with the frequency range of 1.3-1.8 GHz split into 1-MHz channels. STAPS was observed commensally with the S-band Polarization All-Sky Survey (S-PASS). The surveys were conducted using long azimuth scans, which allows STAPS Stokes Q and U to be absolutely calibrated with the data processing procedure developed for S-PASS. STAPS delivers a 20 cm multi-frequency polarization view of the Galaxy, and will help advance our understanding of the Galactic magnetic field and magnetized interstellar medium.

The figure above shows the west and east scans conducted in April and October runs in 2008. The background image displays the total intensity at 1.4 GHz from STAPS. The images are in Galactic coordinates with an Aitoff projection.
