Left: Gaussian restored |F(φ)| spectra of compact sources. B3 0559+422A black solid line, NVSS J060406+422125 blue dashed line, NVSS J060416+422110 (south component) blue solid line, NVSS J060416+422110 (north component) dashed-dotted blue line, NVSS J060231+422811 (west component) red dashed line, NVSS  J060231+422811 (east component) red solid line, and NVSS J060206+422045 black dashed line. The high “residuals” for B3 0559+422A are an artifact due to remaining calibration errors. Right: |F(φ)| spectra, consisting of clean components, extracted at three different positions from relic B. The positions are indicated by the circles drawn in Fig. 19. Red line: position B3, blue line: position B2, and black line: position B1 (see also Fig. 3).
