Full description
This collection contains post-processed image cubes from the POlarization Sky Survey of the Universe’s Magnetism (POSSUM) Pilot 1 survey. These data products include Stokes IQU cubes and corresponding weight cubes for the 10 Pilot 1 survey ASKAP observations. These data are a combination of 10 separate but contiguous 36-beam observations centered on RA (J2000) 321.815° and Dec (J2000) −54.670°. Each field had an integration time of ten hours and the beams were formed in the closepack36 footprint. The survey was observed at full resolution at the ASKAP mid-band frequency range (1152 – 1439 MHz) and averaged to a 288 MHz bandwidth with 1-MHz channel width. The lower half of the band was discarded due to RFI, leaving only the upper 144 frequency channels (1295 – 1439 MHz). These cubes have been leakage corrected using a source based method that involves stacking the 10 observations beam by beam, and fitting residuals with Zernike polynomials to map intensity as a function of distance from the centre of the beam. The cubes have also been convolved to a common 13”x13” resolution across all channels.Notes
