Four-point (240 MHz, 610 MHz, 1.4 GHz, and 5.0 GHz) radio spectra of Seyfert galaxies in our sample. The dotted line connects the flux density points and dashed line shows the least chi-square linear fit to the spectral points. Radio spectra of Seyfert types 1s and 2s are shown in the left and right panels, respectively.
