In the caption for Figure 12.4, there are a couple of small errors:
* Nyquist curves for <math>P_1</math> is solid and <math>P_2</math> is dashed
* The point that is projected is <math>1-i</math>.
The correct caption reads
<blockquote>
Geometric interpretation of <math>d(P_1,P_2)</math>. At each frequency, the points on the Nyquist curve for <math>P_1</math> <font color=blue>(solid)</font> and <math>P_2</math>  <font color=blue>(dashed)</font> are projected onto a sphere of radius <math>1</math> sitting at the origin of the complex plane. The projection of the point <font color=blue><math>1-i</math></font> is shown.
