About IDIA Public Data Archive

The IDIA Public Data Archive, part of the IDIA Science Gateway, hosts released radio astronomy images and catalogues from projects supported by IDIA. The homepage lists several releases, including the superMIGHTEE Data Release 1, the MIGHTEE Continuum Survey Data Release 1, the MIGHTEE Polarization early science data, and MIGHTEE-HI deep spectral line cubes of the COSMOS field.

The archive also includes a set of images and catalogues for software testing and CARTA tutorials. The homepage excerpt does not describe download methods, file formats, licensing or terms of use, so these are not covered here.
