Radio core of NGC 5427 as measured by the VLA A-array at 1.49 GHz (contours are given contours are as a percentage of peak intensity and increase in steps of 2 from the lowest contour of: the peak intensity is 11.8 mJy/beam and the lowest contour of 1.4% of this. A negative contour of –1.4% of peak intensity is also shown as a dashed line). The 1.49–4.86 GHz spectral index is indicated by the colour scale. The source is essentially unresolved, but there is marginal evidence for an elongation in the NW-SE direction. The spectral index is also steeper in these directions suggesting that the very weak jet within 0.2 arcsec of the nucleus is suffering strong synchrotron losses in its passage through the circum-nuclear ISM.
