Continuum images from GMRT 323 MHz. The black crosses denote the published optical positions in Anderson et al. (2001), Fan et al. (2001), Sharp et al. (2001), McGreer et al. (2006, 2009), Willott et al. (2010), Zeimann et al. (2011), Yi et al. (2014), and SDSS. The shapes of the synthesized beams are plotted in the bottom left corner of each sub-figure. The beam sizes are presented in Table 3, where the rms of each map and the flux density of each target are also listed. The contour level, shown by a dashed line, is −3×rms; the contour levels, shown by a solid line, are 3 × 2ⁿ × rms, where n is [0, 1, 2, 3, 4 …].
