Type-II radio sources observed by NRH at different frequencies at 12:03:41 UT. The radio sources are represented by the 80 %, 90 %, and 95 % contours of the corresponding T_Bmax. The last panel compares the various radio sources at different NRH channels observed at 12:03:41 UT. The red ellipse represents the beam shape at different NRH frequencies. The beam size is about ∼53 arcsecs at 408 MHz, ∼66 arcsecs at 327 MHz, ∼ 73 arcsecs at 298.7 MHz, ∼80 arcsecs at 270.6 MHz, ∼95 arcsecs at 228 MHz, ∼125 arcsecs at 173.2 MHz, and ∼144 arcsecs at 150.9 MHz along the major axis, and is about ∼39 arcsecs at 408 MHz, ∼49 arcsecs at 327 MHz, ∼53 arcsecs at 298.7 MHz, ∼59 arcsecs at 270.6 MHz, ∼70 arcsecs at 228 MHz, ∼92 arcsecs at 173.2 MHz, and ∼105 arcsecs at 150.9 MHz along the minor axis.
