Fig. 1.

Wide-field MeerKAT image with a robust −0.5 weighting of the Ophiuchus cluster. The resolution and noise are 6.1″ × 5.5″ and 4.5 μJy beam⁻¹. The circle has a diameter of 67.3′, corresponding to the FWHM $= 57.5' {(\frac{ν}{1.5 GHz})}^{- 1}$ $= 57.5{\prime}\left( \frac{\nu}{1.5\,\mathrm{GHz}} \right)^{-1}$ of MeerKAT computed at ν = 1.28 GHz (Mauch et al. 2020). The color bar units are Jansky beam⁻¹.
