MeerKAT total-intensity and polarization data products for the Abell 3391/95 system

This record contains science-ready MeerKAT total-intensity and polarization data products for the Abell 3391/95 galaxy cluster system, accompanying the paper “Magnetic properties of the Abell 3391-3395 system revealed using wide-field MeerKAT polarimetry.” The deposit includes a high-resolution Stokes I mosaic with an angular resolution of 5.7 × 5.4 arcsec, a peak polarized-intensity map at 9 × 9 arcsec resolution, a 9 × 9 arcsec full-Stokes IQUV image, and a catalog of polarized sources containing their sky positions, residual rotation measures, Galactic rotation-measure estimates, and associated uncertainties. The polarized-intensity map has not been corrected for Rician bias. The observations were obtained with MeerKAT under project SCI-20220822-FG-01. Details of the calibration, imaging, source extraction, and rotation-measure analysis are provided in the accompanying paper.
