SuperMIGHTEE Data Release 1

The first data release from the superMIGHTEE uGMRT observations of the MIGHTEE deep fields. This release consists of Stokes I mosaic images and associated source catalogues from uGMRT observations of XMM-LSS, COSMOS, and ECDFS.

This data release consists of mosaic FITS images at 400 (uGMRT band 3) and 650 MHz (uGMRT band4) of Stokes I emission within the MIGHTEE deep fields XMM-LSS, and 650 MHz images within COSMOS and ECDFS. Angular resolution is approximately 5” and sensitivities are from 10-40 microJy/beam. Source catalogues from pyBDSF source finding on each mosaic are also included.
