Inband total spectral index of the MeerKAT L-band (panel a)) and its uncertainty (panel b)) between the frequencies 0.96 and 1.59 GHz overlaid with radio emission at frequency of 1.28 GHz starting at 3σ and increase by a factor of 2 (σ = 9 μJy/beam). The resolution of 12″ is shown in the bottom left corner. Two-point total spectral index (panel c)) and its uncertainty (panel d)) between ATCA L/S-band (2.1 GHz) and C-band (5.5 GHz) overlaid with radio emission at frequency of 2.1 GHz starting at 3σ and increase by a factor of 2 (σ = 11.3 μJy/beam). The resolution of 7″ is shown in the bottom left corner.
