In this article, the legends for Figs. 4 and 5 were inadvertently omitted; the figures should have appeared as shown below.

Top: CFD predictions of Mach disc radius for βw = 150° and lw = 1.0, with LSQ fits and Richardson extrapolation value. Bottom: percentage difference between ytp and the Richardson extrapolation value, ytp,e, for ranges of MRLdisc and MRLfield

Fig. 5
figure 5

Effect of wedge length, lw, on Mach disc radius, ytp, (top) and incident shock angle at the triple point, βtp, (bottom) for shock angles at the wedge leading edge, βw = 148°, 150°, 152°, and 154°. Lines indicate results from the model, open symbols—CFD results, and solid symbols—model predictions at lw,crit
