Selected epochs illustrating the evolution of each identified knot, showing total (contours) and polarized (color scale) intensity. The beam size is indicated as a green ellipse in the first row. Horizontal black lines indicate the position of the core A0, black line segments within the image indicate the direction of polarization (EVPA). The red line in each row is the linear fit to the knot position. It is present for every knot except B7, whose flux was too low to accurately perform a fit. For each row, the spacing between plots is proportional to time, and the total time span is different and indicated in brackets.
