Derived shock parameters: the shock angle ϑsl,i and flow deflection angle ϕsl,i at the intersection of the sonic line and the TS (i = sw) and that at the BS (i = ism) are displayed together with the compression ratios sj at the TS in nose direction (j = n), the tail direction j = t and at the BS j = ism.

Notes. The sonic lines are poorly defined in the CH-model, and therefore neither the shock angle nor the flow deflection angle are given here. In the pH-model they are difficult to determine because the shock angle smoothly evolves from 90° to the lowest values at the triple point. The easiest way therefore is to calculate them analytically.
