Motion of components in 1156+295. The vertical axis shows the separation in milliarcseconds of the center of the component from the presumed core. Component positions measured at 2 GHz are plotted as squares, and positions measured at 8 GHz are plotted as diamonds. The solid lines represent the best fit of the 2 GHz positions to motion with constant velocity, and the dotted lines represent the same fits for the 8 GHz positions.
