Colour-coded LOFAR image of GB 1508+5714 at 144 MHz with the 1.43 GHz VLA contours from Cheung (2004) overlaid. The LOFAR and VLA restoring beams are shown in the bottom left corner as blue and black ellipses, respectively. The VLA contour levels are drawn at (−1, 1, 2, 4, 8, …) times 0.23 mJу beam⁻¹. The RMS in th VLA data is 0.20 mJy beam⁻¹. The restoring beam size is 1.52″ × 1.03″ with a position angle of −4.44°. The restored LOFAR beam size is 1.08″ × 0.643″ with a position angle of −0.27°.
