uGMRT Band 3 (left) image at 15″ resolution and GMRT 150 MHz (right) narrow band image at 30″ resolution. The image properties are given in Table 2, IM16 (left-panel) and IM21 (right-panel). Contour levels are drawn at [1, 2, 4, 8, …] × 3.5 σ_rms. In both images there is no region below −3.0 σ_rms. The halo and the main relic R1 are recovered well at both frequencies. Images are created with Briggs weighting with robust = 0. The beam size is indicated in the bottom left corner of the each image.
