With 1024x768 resolution, the original alignment had been pushing the
x standard deviation units (nm) off the screen.
\sqrt{\left\langle x_c^2 \right\rangle}
&= \sqrt{\frac{\left\langle V_p^2 \right\rangle}{\sigma_p^2}}
= 0.28 \; \text{nm} \\
- \kappa &= \frac{k_B T \sigma_p^2}{\left\langle V_p^2 \right\rangle}
- = 54 \pm 3 \; \text{pN/nm}
+ \kappa = \frac{k_B T \sigma_p^2}{\left\langle V_p^2 \right\rangle}
+ &= 54 \pm 3 \; \text{pN/nm}
