MIGHTEE Polarization Early Science Data Release

MIGHTEE Polarization early science data images and catalogs.

The early science data release for MIGHTEE Polarization consists of polarization data images and catalogs that cover observations in two fields: COSMOS and XMM-LSS. The catalogs include radio spectral index, redshift information, and Faraday rotation measure synthesis results for 13 267 total intensity radio sources down to a polarized intensity detection limit of ∼20 μJy/bm. Polarized signals were detected from 324 sources.
