Abell 84. LOFAR 144 MHz images (a, c) at different resolutions shown in the bottom-left corners. The optical SDSS image (b) is overlaid with the LOFAR contours. In all images, the LOFAR first contour is drawn at 3σ, where σ is shown in the top-left corners. The next contours are multiplied by a factor of 2. In panels a and c, the X-ray yellow contour is drawn at 3σ, and subsequently spaced by a factor of . In panel c, the cyan dashed line shows the region where source flux density is measured. The black dashed line region is masked out. All pixels below 2σ are blanked. The cluster centre is marked with the grey plus symbol. The grey dashed circle has a radius of R500.
