Fig. 6
Spectral index map constructed using VLA observations at 74 and 330 MHz (matched to a common angular resolution of 70′′). The 5.5, 15, 26, and 40 mJy beam-1 contours from the 330 MHz image are included to facilitate the comparison between spectral continuum and total power features. To create this map the 74 and 330 MHz images were masked at 3σ.
