Images used when analyzing radiative age at kpc scale. The contours are drawn at -1, 1, 2, 4, 8, ..., of the first contour level (3σrms). The synthesized beams are plotted in the bottom left corner of each image. Three components used in the spectral analysis, i.e., NE, core, and NW, are distinguished by two gray dashed lines.
