Figure 8: The solution values for (4)–(7). Horizontal: the maximum jet velocity, . Left vertical: the maximum range of the polar ejecta. Right vertical axis: the distance from the pulsar to the beginning of the polar ejecta. The line with the steepest slope converts (bottom) to (left) or (right), and three values for are marked. The three other lines with moderate slopes constrain the minimum of (right end of 74 mas curve) and the maximum of (left end of the 45 mas curve and also read on the left vertical axis) from offset measurements of the Mystery Spot, which is assumed to be a jet-driven plume within the polar ejecta. Five values of , from 0.3 to 0.7, are tic-marked on the four curves.
