Caption: Figure 6.

The normalized distribution of spectral indices derived from cross-matching with the 1.4 GHz VLA-NVSS (navy) and 150 MHz uGMRT-TGSS (royal blue) surveys is shown as solid lines, using a matching radius of 20″. The assumed power-law spectral index of α = −0.7 is indicated by a dashed line in black.
