Basis functions $h_k\left(v\right)$ (31) and ${\varphi }_k\left(t\right)$ (32) of the Legendre model for two time-scaling factors $\alpha$: (a) $h_k\left(v\right)$, $\alpha =0.05\left[s\right]$; (b) $h_k\left(v\right)$, $\alpha =0.5\left[s\right]$; (c) ${\varphi }_k\left(t\right)$, $\alpha =0.05\left[s\right]$; (d) ${\varphi }_k\left(t\right)$, $\alpha =0.5\left[s\right]$; $k=0,1,2,3,4$.
