Rotated (40°) views of NGC 4217 all on the same scale with the same labels of the structures as in Figs. 2 and 3. Panel 1: Artificial optical B-band image created by combining the u and g filters from SDSS, sharpened by unsharp masked filter of GIMP. The green cutout shows loop structures from dusty filaments. Left: zoom-in, middle: wavelet decomposition applied via GIMP with the first 4 scales shown; right: simple cartoon representing the apparent structures. Panel 2: Hα image from Rand (1996), using an additional edge-detection filter of GIMP. The blue cutout shows loops and extended structures. Left: zoom-in; middle: other gray scale stretch shown; right: simple cartoon representing the apparent structures. The arrows point to extended structures. Panel 3: Radio map from this work (Fig. 2) indicating the investigated structures. The red cross marks the off-center peak position.
