High-resolution VLA (left panel; van Weeren et al. 2017b) and uGMRT (middle panel; Rajpurohit et al. 2020a) images of the northern part of the relic. The red arrows show regions with fine filaments. The spectral tomography map of the same region is shown in the right panel, indicating that the relic is indeed composed of filaments with different spectral indices (Rajpurohit et al. 2021c). For the majority of these regions, the QU-fitting provides a better fit with two Faraday components.
