Summary of radio quantities measured for the diffuse sources in A2061.

LLS Flux P144 Spectral index(*)
(kpc) (mJy) (W/Hz) (α)
NE extension 800 52±5.0 (8.1±0.8)e23 −1.4
Radio Halo 1300 265±26 (4.1±0.4)e24 −1.3
Radio Relic 790 220±22 (3.3±0.3)e24 −0.92±0.05
Trail 760 49±5.0 (7.5±0.8)e23 −1.4

Notes. The NE extension and trail quantities are measured on the 2σrms contours of the 80″ resolution map. The radio halo quantities are measured on the 6σrms contours of the 80″ resolution map. The radio relic quantities are measured on the 30″ resolution map (see text). (*)Value of the spectral index assumed for the radio power calculation (except the radio relic, which is derived in Sect. 3.4). The assumed value for the bridge and trail is based on literature works (Pignataro et al. 2024a; Bonafede et al. 2021).
