43 GHz total (contours) and polarised (colour scale) intensity images of PKS 1510−089 from 2011 September to 2012 April (top) and 2012 April to October (bottom) with S_peak = 2.58 Jy/beam, mJy/beam, and a Gaussian restoring beam = 0.14 × 0.39 mas² at PA = − 10° (in the right bottom corner); contours represent 0.25, 0.5,...,64, 90% of the peak intensity; line segments within the colour scale show direction of linear polarisation; solid lines indicate position of components across the epoch, the core A0, knot K11, and knot K12.
