Erratum for “The Clothoid Computation: A Simple and Efficient Numerical Algorithm” by Miguel E. Vázquez-Méndez and G. Casal

An error in the data listed for Fig. 7 must be corrected. Fig. 7 corresponds to a minimum radius allowed of $R=0.8\mathrm{hm}$, instead of $R=1\mathrm{hm}$. Consequently, the final sentence of the penultimate paragraph of the “Connecting Two Oriented Circles” section should be replaced by “choose ${\mathrm{\Phi }}_0^1=9/8\pi$, ${\mathrm{\Phi }}_0^2=15/8\pi$, $R=0.8\mathrm{hm}$, $\omega =0$.”

The authors would like to thank Loris Lori from Terni, Italy (Centro Sviluppo Materiali and ThyssenKrupp Acciai Speciali Terni), for replicating all examples and pointing out this mistake.
