Integrated radio spectra of the different components (primary lobes and wings) of 4C32.25 and 4C61.23. Colored points indicate the observed flux densities of the primary lobes (green and cyan), and wings (blue and purple). The solid green and cyan lines show the best-fit synchrotron model of the primary lobes, while the blue and purple lines show the best-fit synchrotron models of the wings, respectively. All the models are calculated keeping the injection index, α_int fixed to the value indicated.
