The DR1 products:
Visibilities: These can be accessed through the MeerKAT archive, under proposal ID SSV-20180624-FC-01.
Basic imaging products: Full field of view, with no primary beam correction, available at full resolution only (~7-8ʺ). Consists of a single 16-plane cube with integrated intensity, spectral index, and 14 frequency planes. Useful for full-field searches and source finding.
Access: Basic products
Enhanced imaging products: Primary beam-corrected, showing the inner 1.2° x 1.2° of the field. Available at both full- (~7-8ʺ) and convolved 15ʺ-resolutions. There are two types of enhanced products: five-plane cubes consisting of intensity and spectral index, associated uncertainties, and the χ² of the combined to fit; and, frequency cubes consisting of 12 frequency planes with centre frequencies of 908, 952, 996, 1044, 1093, 1145, 1318, 1382, 1448, 1482, 1594, and 1656 MHz.
Access: Enhanced products
There are several source catalogues made available with the DR1 products, with excerpts provided in Tables in the DR1 paper.
Compact source catalogue (Table 2):Download
Consists of ~626,000 compact sources from all the MGCLS cluster fields, found using PyBDSF. The sources have an IAU source designation of MKTCS JHHMMSS.ss+/-DDMMSS.s. The catalogue includes source flux density and peak brightness, and associated uncertainties, and source size. Sources have been excised around the brightest sources in each field to reduce the number of spurious PyBDSF identifications of bright source artefacts.
The full PyBDSF output from each cluster field, without any artefact excision, can be found here.
Optical/IR cross-matched catalogue for Abell 209 and Abell S295 (Table 3):Download Compact radio sources in the Abell 209 and Abell S295 fields, cross-matched with DECaLS.

Radio-detected star forming galaxies belonging to the Abell 209 cluster (Table B1):Download
The optical/IR cross-matched compact radio sources in Abell 209 which are identified as star forming galaxies. Catalogue includes the projected distance from the cluster centre, the galaxy star formation rate, the spectroscopic redshift (if available), and the associated 100 μm flux density from Herschel data (if available).
