The original version of this article contains mistakes in Equations, Figure 6, and Table 2.

The variables in equations (5)–(16) should all be lowercase to indicate that they are nondimensionalized.

On page 8, the period of \(f(p_2,p_{13},\tau) = p_2\text{sin}^2(p_{13}\tau)\) is listed as \(\dfrac{2 \pi}{p_{13}}\). However, the correct period is \(\dfrac{\pi}{p_{13}}\).

A sentence on page 8 currently reads, “Figure 6 shows that the minimum of the PIF1-RVE1 periodic solution increases for larger values of p2 and decreases for smaller values of p2, varying somewhat with p13.” The sentence should read as follows: Figure 6 shows that the minimum of the PIF1-RVE1 periodic solution decreases for larger values of p2 and increases for smaller values of p2, varying somewhat with p13.

In Table 2, \(s_{1} = \frac{{d_{bp} }}{{d_{p} }}\). It should read \(s_{1} = \frac{{d_{p} }}{{d_{bp} }}\).
