Our ASKAP mosaic image of SB8275 covering the Abell 3391-95 system and surrounding sources after direction-dependent calibration. Magenta contours are at 4σ and cyan contours are 6σ × l where l is [1, 2, 8, 32,128, 512, 1024, 2048] and σ = 36 μJy beam⁻¹. White dashed contours are − 4σ. All sources highlighted and magnified in this image fall within the mean redshift of the cluster system except for F3 which is at z = 0.193. Details on these sources are summarised in Tables 2 and 3.
