Galaxy NGC 0628 -  Left panel: the color scale represents the image of the spectral index measured between 327 MHz and 1.4 GHz. Pixels with an intensity level above 3$\sigma $ at both frequencies have been considered. Contours levels of the radio image at 1.4 GHz, starting from 3$\sigma $ and scaling by a factor of $\sqrt {2}$, are overlaid on the image. The FWHM of this image is $66\hbox {$^{\prime \prime }$ }\times 66\hbox {$^{\prime \prime }$ }$. Right panel: the color scale represents the image of the spectral index uncertainty.
