Spectral index maps generated by applying the identical analysis as conducted in Section 3.2, but using the 22 and 43 GHz images with a restoring beam size equal to the original beam size multiplied by f_mul. The results for f_mul = 1.25, 1.50, 1.75, 2.00 are displayed from left to right. The position of the knot identified through WISE analysis is indicated by cyan crosses. The presence of the inverted spectral region near the knot’s deflection point persists even with a larger restoring beam size, although the contrast diminishes in comparison to the original spectral index map (Figure 6).
