TGSS (left panel) and NVSS images (right panel) of the PSR B1620-26 field at 150 MHz and 1.4 GHz. The green ellipse in the lower-left corner (of these images and other images presented in this paper) shows the half power beamwidth (~20′′for TGSS). The contour levels given at the top of the image (and other images presented in this paper) are in units of Jy beam^-1 and are defined as mean+rms × (n), where n is given inside the brackets in the top label. Negative contours appear as dashed lines. The host star position is given by the blue cross. Here in the NVSS image the contour of the emission is well centered on that position.
