Appendix 4—table 1. Value of $G(t,\tau )$ for different possibilities.

For odd or even number of reversals occurring between time $t$ and $t+\tau$, corresponding cases of initial and final values for state function h and Heaviside function H are considered. Substituting $h$ and $H$ values in (3), G is calculated for each case.

Number of reversals	$h\left(t\right)$	$h(t+\tau )$	$H\left(t\right)$	$H(t+\tau )$	$G(t,\tau )$
Even	1	1	1	1	${\left(1+a\right)}^2$
Even	−1	−1	0	0	1
Odd	1	−1	1	0	$-(1+a)$
Odd	−1	1	0	1	$-(1+a)$
